Abstract
In this work we combine magnetization, pressure dependent electrical resistivity, heat capacity, nuclear magnetic resonance (NMR), and x-ray resonant magnetic scattering experiments to investigate the physical properties of the intermetallic compound. Our single crystals show an antiferromagnetic ordering at K and the magnetic properties indicate that this compound is an Ising antiferromagnet. In particular, the low temperature magnetization data revealed a spin-flop transition at K when magnetic fields of about T are applied along the axis. Moreover, the x-ray magnetic diffraction data below revealed a commensurate antiferromagnetic structure with propagation wave vector with the moments oriented along the axis. Furthermore, our heat capacity, pressure dependent resistivity, and temperature dependent NMR data suggest that exhibits a weak heavy fermion behavior with strongly localized electrons. We thus discuss a scenario in which both the anisotropic magnetic interactions between the ions and the tetragonal crystalline electric field effects are taking into account in .
