Abstract
X-ray magnetic circular dichroism (XMCD) at the rare-earth (RE) L 2,3 absorption edges of RFe2 (R = RE) in the Laves phase has been investigated based on the tight-binding model with the intra-atomic exchange interaction between 5d and 4f electrons. We find that the magnetic polarization of 5d electrons, being essential for these XMCD, is dominated by the intra-atomic exchange interaction and by the hybridization with spin-polarized Fe 3d states. These contributions as well as the quadrupole one compete, resulting in a variety of XMCD spectra, as observed in experiments.
