Abstract

We propose a mechanism of the magnetic circular X-ray dichroism (MCXD) at the pre-peak of the Fe K-edge in Fe-oxides. It is found that the hybridization between the 3d state and the 4p state of Fe ions at tetrahedral sites through the ligand 2p state is responsible for the weak electric-dipole absorption at the pre-peak while the spin-orbit interaction and the spin polarization in the 3d state play a crucial role in MCXD. The important effects of the configuration interaction as well as of the core hole are discussed in connection with the asymmetric dispersion-type MCXD observed in rare-earth iron garnets and magnetites.
