Show affiliationsWe have studied Bi L-edge X-ray magnetic circular dichroism (XMCD) of Bi substituted Gd iron garnet (BiGd-IG) by using the relativistic multiple scattering calculations. BiGd-IG has giant magneto-optical response with substituted Bi. The XMCD analysis is suitable to understand the interesting behavior; it is important to understand the local magnetic and electronic structure around absorption atom Bi. Comparing the experimental spectra, we find that the proportion of magnetic atoms to nonmagnetic ones around Bi strongly influence the Bi XMCD spectra. We also investigate the effects of the spin polarization of the Bi 6p states.
