Abstract

The electronic structure and x-ray magnetic circular dichroism (XMCD) spectra of the Heusler alloy Co(2)FeGa were investigated theoretically from first principles, using the fully relativistic Dirac linear MT-orbital (LMTO) band structure method. Densities of valence states, orbital and spin magnetic moments are analyzed and discussed. The origin of the XMCD spectra in the Co(2)FeGa compound is examined. The calculated results are compared with available experimental data. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3654132]
