The relation between magnetic circular dichroism (MCD) and the local magnetic properties of metal can be derived in the frame of spin polarized multiple scattering theory. Green's function is used to solve the Dyson's equation of multiple scattering. Here we have used a non relativistic approach by treating spin-orbit as a perturbation of the multiple scattering development using a spherical potential. By this method, we can interpret the real process within atomic level, hence we can correlate the difference in x-ray absorption due to spin to the properties of nano magnetic material. We have tested the theory on iron, cobalt, and nickel. We found that we obtain a good order of magnitude compared with XANES (x-ray absorption near edge spectroscopy) experiment.
