Description

In this work we theoretically study magnetic EXAFS based on relativistic scattering theory. So far Fourier transform of magnetic EXAFS has been believed to give no peak for the backscattering from nonmagnetic atoms. We carefully study this problem for two examples, Gd L23-edge EXAFS for Gd3Fe5O12 and Mn K-edge EXAFS for Ni1-xMn x alloys, and find that even nonmagnetic nearest neighbors can give a prominent peak in Fourier transform of magnetic EXAFS as far as the X-ray absorbing atom is strongly spin polarized. We also investigate the effect of the integral region in the Fourier transform
