An implementation of the multiple-scattering approach to x-ray magnetic circular dichroism (XMCD) in K edge x-ray absorption spectroscopy is presented. The convergence problems due to the cluster size and the relativistic corrections are solved using an expansion of the Dirac Green function for complex energies up to second order in 1/c. The Fermi energy is dealt with via a complex plane integration. Numerical methods used to obtain the semirelativistic Green function in the whole complex plane… 
Relativistic multiple scattering theory of K-edge X-ray magnetic circular dichroism
Abstract We discuss the angular dependent K-edge X-ray magnetic circular dichroism (XMCD) spectra based on the non-relativistic Green’s function expansion of the relativistic 4×4 Green’s function
Measurement and multiple-scattering calculation of Cu K-edge x-ray magnetic circular dichroism spectra from an exchange-coupled Co/Cu multilayer
Small but significant x-ray magnetic circular dichroic (XMCD) absorptions are observed from an exchange-coupled Co/Cu multilayer at the Cu K edge. Multiple-scattering calculations including the

TLDR
Ab initio calculations have been made using the fully relativistic Korringa-Kohn-Rostoker formalism including the spin-orbit coupling to explain the remarkable oscillations observed in the x-ray magnetic circular dichroic absorption spectra from Gd/Cu multilayers at the Cu K edge.
Multiple-scattering approach to magnetic EXAFS
The existence of oscillations far from the edge in magnetic circular dichroism (MCD) spectra in the X-ray range were first observed by Schlitz and coll. [1]. A number of subsequent experimental and

Magnetic circular dichroism in hard x-ray Raman scattering as a probe of local spin polarization
We argue that the magnetic circular dichroism (MCD) of the hard x-ray Raman scattering (XRS) could be used as an element selective probe of local spin polarization. The magnitude of the XRS-MCD
