Electronic structure and X-ray spectroscopy of Cu${}_2$MnAl${}_{1-x}$Ga${}_x$

Abstract

We explore the electronic and related properties of Cu${}_2$MnAl${}_{1-x}$Ga${}_x$ with a first-principles, relativistic multiscattering Green function approach. We discuss our results in relation to existing experimental data and show that the electron-core hole interaction is essential for the description of the optical spectra especially in describing the X-ray absorption and magnetic circular dichroism spectra at the L${}_{2,3}$ edges of Cu and Mn.
