Název v původním jazyce

Field-induced magnetic transitions in the highly anisotropic ferrimagnet ErFe5Al7 studied by high-field x-ray magnetic dichroism

Popis výsledku v původním jazyce

We present a comprehensive study of the magnetic properties of the strongly anisotropic ferrimagnet ErFe5Al7 in pulsed magnetic fields up to 30 T applied along the hard magnetization axis within the basal plane of the tetragonal lattice around the compensation temperature (Tcomp). Macroscopic measurements showed two anomalies at about 8 T and 25 T in a small temperature range around Tcomp. High-field x-ray magnetic circular dichroism (XMCD) data at the Er M5- and the Fe L3-edge resonances provide insight into the element-selective magnetization processes, revealing a coherent rotation of Er-4f and Fe-3d moments, with stepwise jumps including an unexpected one from an easy to a hard magnetization axis. XMCD at the Er L3-edge resonance elucidates the role of Er 5d electrons in coupling Er-4f and Fe-3d moments. In-plane anisotropy constant was evaluated from a simulation of the magnetization process at temperatures well below Tcomp using a two-sublattice model.
