Abstract: One of the most exciting features of the hole centers CuO45- in doped cuprates is in their unusually complicated ground state as a result of electronic quasi-degeneracy. An additional hole, doped to the basic CuO46- cluster with the b1g hole can occupy both the same hybrid Cu3d-O2p orbital state resulting in a Zhang-Rice singlet 1A1g and the purely oxygen eu molecular orbital resulting in singlet or triplet 1,3Eu  term with the close energies. We present a detailed analysis of the (pseudo)-Jahn-Teller effect driven by the near-degeneracy within the (1A1g, 1,3Eu)-manifold.

Abstract: The experimental study of the electron spin-lattice relaxation (SLR) of Nd3+ and Tb3+ ions in phosphate and sodium borate silica glasses was performed. Measurements were made with electron spin echo technique. Temperature dependences of spin-lattice relaxation of the rare earth ions reveal the contribution of different relaxation mechanisms. A stepped like change of the SLR rate observed for Tb3+ and Nd3+ ions was explained by cross relaxation.

Authors: A. Sinicin, S. Borcov, V. Nadolinny*, I. Kireenko, V. Kirillov
Address: Institute of Inorganic Chemistry Siberian Branch of RAS, Novosibirsk, Russia
*e-mail:

Abstract: The influence of micro plasma oxidation (MPO) process conditions on creation of the Al2O3 coatings on aluminum alloy D16 was studied using EPR technique. Aluminum alloy D16 contains alloyed transition metals such as Cu, Mn, Fe, Ni, Ti, being incorporated into the coatings structure during MPO processes. EPR data on transition metal ions allow estimating an appearance of a high temperature phase of Al2O3 due to difference in incorporation coefficients and in the EPR parameters of transition metal ions in low and high temperature Al2O3 phases of MPO coatings. These data show that no high temperature Al2O3 phases were created during anodic MPO process.

Title: Binding energy of a Cooper pairs with non-zero center of mass momentum in d-wave superconductors
Authors: M.V. Eremin, I.E. Lyubin*
Address: Kazan State University, Kremlevskaya, 18, Kazan 420008, Russia
*e-mail:

Abstract: The binding energy of Cooper pairs has been calculated for the case of d-wave symmetry of the superconducting gap in layered cuprate superconductors. We assume that Cooper pairs are formed by the short range potential and then derive the binding energy in the form \Delta _{{\mathbf{kq}}} = \Delta _x ({\mathbf{q}})\cos k_x a + \Delta _y ({\mathbf{q}})\cos k_y a + \Omega _x ({\mathbf{q}})\sin k_x a + \Omega _y ({\mathbf{q}})\sin k_y a, where q  is a total momentum of the pair. Numerical solutions of the self-consistent system of the integral equations for quantities \Delta _x ({\mathbf{q}}) , \Delta _y ({\mathbf{q}}) and \Omega _x ({\mathbf{q}}), \Omega _y ({\mathbf{q}}) along different lines in qx, qy  plane have been obtained. Anisotropy of the depairing total momentum (or depairing current) has been calculated.

Abstract: Anthraquinone paramagnetic complexes have been used to study electron-acceptor centers on the surface of alumina modified with alkali metal ions (Li+, Na+, K+). Complexes have been characterized by CW EPR, ENDOR and pulse EPR (HYSCORE) techniques. It has been shown that alkali metal ions decreased the strength of electron-acceptor centers due to the inductive effect. As a result the concentration of anthraquinone complex with two Lewis acid sites (LAS) decreased, but the concentration of complex with one LAS increased with the increasing of alkali metal content. At large alkali metal concentration other kinds of anthraquinone paramagnetic complexes are formed, that are anthrasemiquinone weakly bound with LAS as well as anthrasemiquinone ion pair with alkali metal cation (lithium).

Abstract: Electron states near the surface of small metal particle caused by an image charge (image-potential states) have been investigated. The wave functions were calculated and the energy spectrum of these states was found depending on particle size. To estimate the influence of static magnetic field on the image-potential states the model problem, in which electron is localized on a surface of a sphere in uniform magnetic field was solved. In this case the field dependence of the energy levels represents a complex level crossing structure.

Abstract: The investigations of Ag-contaning tennantite, belonging to the group of tetrahedrite-based sulfides, were performed by means of copper nuclear quadrupole resonance (NQR) in a temperature range from 4.2 K up to 60 K. These experiments showed that copper nuclear spin-lattice relaxation rate T1-1 and nuclear spin-echo decay rate T2-1 depend on temperature in the same way as earlier studied samples with other impurity compositions. The obtained data are interpreted from the viewpoint of internal motions in the structure of tennantite. The analysis of copper NQR data at low temperatures points to magnetic phase transition near 60 K from paramagnetic phase to the phase, which resembles spin-glass-like constitution.

Abstract: The asphaltene powders have been studied by 1H NMR relaxation method, differential scanning calorimetry (DSC) and X-ray structure analysis. The asphaltene samples were extracted from three oils with different component and hydrocarbon-group compositions. It was found that free induction decays (FID) of various asphaltene samples contain Gaussian component with spin-spin relaxation times T2 about 10?20 μs, which was named a solid component. The detecting possibilities of equilibrium first-order phase transitions and non-equilibrium glass-transitions on temperature dependence of part Ps of solid component in the 1H NMR signal are presented. The 1H NMR relaxation and DSC methods to study temperature properties of asphaltenes are compared. The glass-transition temperatures of side aliphatic chains of asphaltene molecules are measured. We set up that crystallization of high-molecular side aliphatic chains of asphaltene molecules is possible.

Abstract: Temperature dependences of ferromagnetic resonance spectra of nanoparticles of magnetite dispersed in polyethylene glycol films and nickel in vaseline oil have been studied. Sharp changes in spectra position (g-value) and linewidth have been found for both systems in the temperature interval 60 - 100 K above glass transition point. These effects have not been observed for polyethylene glycol films prepared under external magnetic field. It has been shown that the effects observed are connected with formation of anisotropic aggregates from nanoparticles under magnetic field action. The main factors determining the temperature of spectra parameters changes are the matrix viscosity, particles translational mobility and spectrum sweeping time.

Abstract: X-band ESR of chemically dehydrofluorinated poly(vinylidene fluoride) films has been studied in the 150 ? 375 K temperature range. Dehydrofluorinated films reveal an ESR signal with g-factor close to that of the free electron. The ESR parameters (integral intensity, width, g-factor) of the samples depend on duration of the chemical reaction, storage conditions and temperature. Heating above 375 K modifies paramagnetic component of the samples stored in air irreversibly, probably, as a result of hydrogenous radicals desorption and/or removal of oxygen, hydroxyl groups and moisture from the samples on heating. The deviation from the Curie law has been revealed for all the investigated samples.

Abstract: Nuclear magnetic resonance (NMR), Raman spectroscopy and thermogravimetric methods were used to study the peculiarities of lithium ion replacement by protons in lithium metallates Li2MO3 (M=Ti, Zr). In this article we show that almost all protons in the final substitution products H2MO3 enter into the crystal structure. All protons in zirconium hydroxide belong to hydrogen-bonded OH-groups. Contrary, titanium hydroxide contains both hydrogen-bonded and isolated OH-groups. Protons in H2ZrO3 form hydrogen bonds weaker than in H2TiO3.

    Abstract: To study the effects of dynamic nuclear polarization (DNP) in the X-band (microwave frequency of 9 GHz), using the capabilities provided by commercial EPR equipment, a part of the EPR spectrometer associated with the excitation and detection of double electron-nuclear resonance signals (ENDOR) has been modernized. Using the developed preamplifier of NMR signals, a homemade "Kazan Nova II" NMR spectrometer was implemented into the radio frequency path of the EPR spectrometer. The tuning and matching circuits made it possible to observe the NMR and DNP signals on protons in the frequency range 14.5-15.2 MHz. The performance of the DNP equipment was tested for a solution of the stable nitroxyl radical TEMPOL in benzene and a crude oil sample. The DNP effects caused by the Overhauser and solid effects were observed. The modernization of the existing EPR equipment creates a basis for further expanding its capabilities to study DNP effects in various systems at different conditions (in the pulsed mode of saturation of the EPR lines, with the temperature lowering, under the action of optical excitation, etc).

    Title: Two-pulse double quantum and five-pulse double-quantum modulation sequences in EPR: Coherence transfer and distance measurements

    Abstract: Double-quantum (DQ) coherence transfers and signals in two-pulse DQ and five-pulse DQM (double quantum modulation) pulsed EPR sequences, utilized for orientation selectivity and distance measurements in biological systems using nitroxide biradicals, have been calculated here for X-band (9.26 GHz) pulsed EPR (electron paramagnetic resonance) using a rigorous numerical algorithm. It is shown, in general, that both, a finite (selective) pulse, rather than an infinite (non-selective) pulse, and the dipolar interaction between the two nitroxide radicals, are needed to produce non-zero coherence transfers in 0→2 and 2→-1 transitions. Furthermore, the simulations show that there exits orientational selectivity, as exhibited by the large value of the coherence transfer probability, T0→2, for those coupled nitroxides, whose dipolar axes, relative to the external magnetic field, are oriented symmetrically, within a small region, within about ±10° away from the magic angle θ = 54.74° and its supplementary angle θ = 125.26°. It increases monotonically as the amplitude of the irradiation field (B1) decreases. The magnitudes of the coherence transfers in the transitions 0→2 and 2→-1 are found to be about the same. They depend upon both, the amplitude of B1 and the duration of the pulse. As well, they increase significantly with increasing d, as found for d=10.0, 20.0, 30.0 MHz, where d=2D/3, with D being the dipolar-coupling constant. The numerical calculations, using Monte-Carlo averaging, reveal that the Pake doublets occur at ±3d/4$ and ±d for the two-pulse DQ and the five-pulse DQM sequences, respectively, as calculated for d=0.5, 7.0, 10.0, 20.0, 30.0, 40.0, 50.0 MHz. It is seen that for d = 0.5 MHz, considered here, for which the modulation depth can be measured within the dead-time, the dipolar depth of the modulation is ≈100%, which indicates that the DQ and DQM sequences are more efficient for distance measurements as compared to other techniques, e.g., DEER (double electron-electron resonance). The numerical algorithm for the five-pulse DQM sequence presented here is exploited to provide a good fit to the published experimental data. Simulations were also carried out at Ku-band (17.6 GHz), which showed that there occur no orientational selectivity at this band, unlike that at X-band. On the other hand, the signals and their Fourier transforms are found to be relatively more intense at Ku-band.

    Abstract: Spin-carrying defects possessing optically addressable ground states in semiconductors allow the development of solid-state quantum technologies. Recently such type of defect has been found in hexagonal boron nitride (hBN) and identified as a negatively charged boron vacancy (VB-). Here we investigate the possibility to create VB- centers in hBN by irradiation with high-energy protons (EP= 15 MeV), and probe the spin-coherence of the defects. Electron paramagnetic resonance methods show that such irradiation generates the VB- centers. Spin-relaxation times (T1 and T2) of VB- spin ensembles created by proton irradiation are determined to be 20 μs and 4 μs, respectively.

    Abstract: A comparative study of the formation mechanism of a single-pulse echo and its analog formed jointly by radio-frequency and two magnetic video-pulses, when their amplitude exceeds the pinning force of domain walls, is carried out. The results obtained support the assumption that the single-pulse echo signal is formed by the mechanism of local field distortions at nuclei in domain walls when they are displaced by RF pulse fronts due to the inhomogeneity of the hyperfine field and the NMR amplification factor in the domain walls.

    Abstract: The magnetic resonance properties of a low-dimensional cobalt-Al2O3-germanium tunnel contact are studied in this work. The appearance of minima observed at low temperatures on both sides of the cobalt layer was found on the thermomagnetic curve. The value of the temperature minimum differs in magnitude on both sides of the cobalt layer. The position of the minimum in the temperature dependence of magnetization depends on the sample preparation technology. As a result of layer growth, at least two magnetic phases appear. One contribution is from the spins of ferromagnetic particles (cobalt particles with a hexagonal close packed lattice), and additional contributions from the magnetically disordered phase of fine cobalt particles and Co-Al2O3 compounds.

    Abstract: The spin dynamics of the Sr2MnTiO5.87 double perovskite have been studied via the magnetic resonance method. Two Lorenz lines below 100 K were used to describe magnetic resonance spectra. Using the Kawasaki-Mori-Huber and Vogel-Fulcher equations, the temperature dependence of the ESR line widths near the magnetic phase transition temperature have been described. The analysis of the line width in high-temperature limit allowed us to estimate the parameters of single-ion anisotropy and antisymmetric exchange interactions.

    Abstract: The point defects have been produced in the rutile structure by irradiation of a single crystalline (001)-TiO2 rutile platet wih 40 keV Ar+ ions. It is found that Ar-ion bombardment of rutile results in a large number of positively charged oxygen vacancies and, as a consequence, leads to a change in the valence of neighbouring Ti cations. Electron paramagnetic resonance (EPR) of Ar-ion irradiated TiO2 rutile is studied in detail. The analysis of angular and temperature dependences of EPR spectra makes it possible to conclude that EPR signals are associated with Ti3+ ions in the sixfold symmetric environment. In addition to the main signal from even titanium isotopes, eight equidistant weak lines are observed due to the hyperfine interaction typical for two titanium isotopes: 47Ti with a nuclear spin I=5/2 (natural abundance of 7.4%) and 49Ti with a nuclear spin I=7/2 (natural abundance of 5.4%). By comparing the g-tensor components with the reference data it is concluded that these Ti3+-based centers in Ar-ion implanted rutile were not described before.

    Abstract: In this research, we propose a model of an impurity nitrogen center in tricalcium phosphate (TCP). This impurity was not intentionally added but was detected by electron paramagnetic resonance (EPR). It was shown that the EPR spectrum of the powder under study is due to two types of such impurity centers, which we attribute to the TCP phase and the admixed hydroxyapatite phase. The parameters of the spin Hamiltonian for the center in TCP obtained using Density Functional Theory (DFT) calculations are close to the experimental ones and allow us to propose a model of a nitrogen-containing center. The temperature dependence of the spin-lattice relaxation rate in the TCP phase is described by a process proportional to T2.35 in the temperature range from 10 to 300 K.

    Abstract: The magnetic system of the Li2CuCrO4 compound is characterized by the formation of helical spin structures in CuO2 chains due to strong frustrations of the exchange interaction. The double position of lithium ions determines the existence of the dielectric glass state at T<=70 K. In this work, using the NMR technique, we found the activation energy of the dipole glass system Ea = 101 K and determined the type of helicoidal copper spin structure as a "screw". It was demonstrated how the high-temperature interaction of strongly correlated spin and dielectric subsystems in this compound paradoxically prevents the appearance of multiferroic behavior in the ordered phase.

    Abstract: The low-cost device for optical detection of magnetic resonance (ODMR) has been developed for use with commercial electron paramagnetic resonance spectrometers. The equipment is based on a scheme with coaxial optical fibers, where the excitation is transmitted through a central fiber with a diameter of 400 μm, and the photoluminescence signal is collected using seven optical fibers with a diameter of 200 μm. The device has the ability to modulate the excitation radiation, microwave frequency and magnetic field. The ODMR attachment has been tested on standard and well-known NV - (nitrogen-vacancy) paramagnetic centers in diamonds. ODMR experiments were carried out in the X-band (9.4 GHz) frequency range with a magnetic field B0 sweeping from 220 to 470 mT. The best signal-to-noise ratio was obtained by modulating of the magnetic field.

    Abstract: We present the results of the quantum calculation of the ground state energies and magnetic g-factors of two rare earth (RE) ions: Yb3+ in Y2Ti2O7 crystal and Er3+ in YPO4 crystal. The Variational Quantum Eigensolver (VQE) algorithm has been performed on 5-qubit IBM superconducting quantum computers via IBM Quantum Experience cloud access. The Hamiltonian of the lowest spectroscopic multiplet of each RE ion, containing crystal field and Zeeman interaction, has been projected onto the collective states of three (Yb3+) and four (Er3+) coupled transmon qubits. The lowest-energy states of RE ions have been found by minimizing the mean energy in ∼ 250 - 350 iterations of the algorithm: the first part was performed on a quantum simulator, and the last 25 iterations were conducted on the real quantum computing hardware. All the calculated ground-state energies and magnetic g-factors agree well with their exact values, while the estimated error of 2÷15% is mostly attributed to the decoherence associated with the two-qubit operations.

    Abstract: Double perovskite Sr2CoNbO6-δ was obtained using a novel pyrolysis method involving nitrate-organic mixtures of the corresponding components and studied by means of XRF, magnetization-based, and EPR methods. The oxygen content equal to 5.4 was obtained from X-ray fluorescence analysis and magnetization data. The effective magnetic moment is 4.05 μB per cell, that corresponds to the theoretical values. The phase transition to an ordered state in the temperature range of 5÷300 K was not detected. The antiferromagnetic nature of exchange interactions between the spins of cobalt ions is confirmed by the negative sign of the Curie-Weiss temperature Θ=-50 K obtained via fitting the inverse magnetic susceptibility. An exchange-narrowed line from cobalt ions is observed in the EPR spectrum in the temperature range of 5÷80 K. A sharp increase in the linewidth at 80 K is associated with the dynamic Jan-Teller effect.

    Abstract: Coordination biopolymers, namely, nickel complexes of sodium pectate, have been actively studied in recent years as promising representatives of non-platinum catalysts for proton exchange membrane fuel cells. The structure of coordination polymers consisting of natural precursors is complex and not entirely regular. It presents significant difficulties in determining the internal structure of coordination polymers. Identifiable electron paramagnetic resonance (EPR) signals of various Mn2+ units in sodium pectate manganese complexes have provided important structural information in systems similar in composition to nickel coordination biopolymers. In addition, the manganese complexes with the natural pectin polymers themselves are of interest as non-platinum PEMFC catalysts.

    Abstract: Hydroxyapatite (HAp)-based materials doped with rare earth elements (REE) have shown applications as biomaterials, lighting emitting materials, scintillating materials, in vivo imaging probes, and thermoluminescent dosimeters. Gadolinium-containing calcium phosphates are promising contrast agents for various bioimaging modalities. In this work, hydroxyapatite materials with gadolinium ion impurities with a 0.44 mol.% concentration were obtained by wet chemical precipitation. Samples after chemical synthesis (as-dried) and heat treatment were studied using electron paramagnetic resonance (EPR) spectroscopy in continuous wave and pulsed modes. Analysis of the EPR spectra made it possible to establish the incorporation of Gd3+ ions in the structure of HAp in two calcium positions with different parameters of the spin Hamiltonian. Heat treatment of samples at a T = 1300°C leads to a significant change in the EPR spectra of Gd3+ ions with a decrease of the uncontrolled nitrate anion centers (synthesis by-product) concentration.
