| Description: |
International audience ; We present a comprehensive study of the magnetic properties of the strongly anisotropic ferrimagnet ErFe 5 Al 7 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 (T comp ). Macroscopic measurements showed two anomalies at about 8 T and 25 T in a small temperature range around T comp . High-field x-ray magnetic circular dichroism (XMCD) data at the Er M 5- and the Fe L 3 -edge resonances provide insight into the element-selective magnetization processes, revealing a coherent rotation of Er 4 f and Fe 3d moments, with stepwise jumps including an unexpected one from an easy to a hard magnetization axis. XMCD at the Er L 3 -edge resonance elucidates the role of Er 5d electrons in coupling the Er 4 f and the Fe 3d moments. Finally, an in-plane anisotropy constant was evaluated from a simulation of the magnetization process at temperatures well below T comp using a two-sublattice model. |
