SPIN-POLARIZED AND ORBITAL-POLARIZED MULTIPLE-SCATTERING THEORY OF MAGNETO-X-RAY EFFECTS IN FE

A theoretical approach of various magnet-X-ray effects (Faraday rotati on, resonant magnetic X-ray scattering a well as magnetic circular dic hroism) based on spin-and orbital-polarized relativistic multiple scat tering theory, is outlined. The results of this approach applied to bc c Fe K and L-2.3 edges are compared with experiments. It is found that the orbital-polarization (correction) only slightly affects the L-2.3 edge Faraday rotation and resonant magnetic X-ray scattering although it significantly increases the orbital moment and the magnitude of th e K edge magneto-X-ray spectra.
