Methods to Study Magnetotactic Bacteria and Magnetosomes
2018, Methods in MicrobiologyCitation Excerpt :The spatial resolution far beyond the Rayleigh criterion and femtosecond temporal resolution can be generated. A small collecting aperture close to the sample surface was scanned and the image appeared (Barbara, 1996). However, the limitation of a small planar area and the requirement of considerable time for image analysis and interpretation hinder its further utilization in the determination of MS magnetism (Carvalho, Inácio, Miranda, & Santos, 2017).
Ferrite Materials: Nano toSpintronics Regime
2015, Handbook of Magnetic MaterialsCitation Excerpt :In magnetism, for example, a typical size of a magnetic domain is of the order of 1 μm and particles much smaller than that will be single domain. Another scale involves exchange coupling effects, which affects the magnetic polarization of neighboring ferromagnetic particles in nonmagnetic hosts, have a range of the order of several nanometers (Barbara, 1996; Hernando, 1993) It is important to realize that the “nano” in magnetism is not uniquely defined.
Magnetic and electric properties of C-Co thin films prepared by vaccum arc technique
2011, Journal of Alloys and CompoundsCitation Excerpt :In the past two decades, nanocrystalline magnetic materials made of metallic nanoclusters dispersed in an amorphous matrix have attracted considerable interest owing to their electrical [1–3] and magnetical [4–7] properties for applications such as sensors, electrode devices, optic components and for fundamental research [8,9].
Exchange bias in nanostructures
2005, Physics ReportsCitation Excerpt :Moreover, the industrial demand to systematically reduce the size of spin valve and other exchange bias based devices is also fueling new research in lithographically fabricated exchange biased nanostructures. From the more basic point of view, it is well known that a range of novel properties arise, in both FM and AFM materials, as the size is reduced (e.g., increased importance of surface effects, changes in the magnetization reversal modes or superparamagnetism) [47–78], hence it is appealing to investigate how does size reduction affect FM–AFM coupled systems. Additionally, the interest in proximity effects, which have been shown to be enhanced in nanostructured systems, because an appreciable fraction of the electronic wave function resides outside the physical extension of the nanostructure, are also generating an increased interest in FM–AFM nanostructures [63,79].
