Abstract

Results of a previously developed fully relativistic theory of magnetic EXAFS (MEXAFS), that has been set up in the framework of relativistic multiple scattering theory, are presented. The multiple scattering process in the final states is treated using matrix inversion technique for finite clusters. The K- and L 2,3-edge spectra of FCC-Ni are calculated on the basis of the Dirac equation for spin-polarized, magnetic solids and compared with experiment. As for the magnetic circular X-ray dichroism in the near-edge region, it is shown that the magnetic EXAFS spectra can be interpreted on the basis of the so-called sum rules.
