%X We present a comprehensive study of the magnetic properties of the strongly anisotropic ferrimagnet ErFe<sub>5</sub>Al<sub>7</sub> 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<sub>comp</sub>). Macroscopic measurements showed two anomalies at about 8 T and 25 T in a small temperature range around 𝑇<sub>comp</sub>. 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 4⁢𝑓 and Fe 3⁢𝑑 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 5⁢𝑑 electrons in coupling the Er 4⁢𝑓 and the Fe 3⁢𝑑 moments. Finally, an in-plane anisotropy constant was evaluated from a simulation of the magnetization process at temperatures well below 𝑇<sub>comp</sub> using a two-sublattice model.
