Abstract
Mn 3d electronic structure in IV–VI ferromagnetic semiconductor Ge 1− x Mn x Te ( x = 0.32) has been investigated by means of the soft X-ray magnetic circular dichroism (XMCD) measurements of the Mn 2p-3d absorption spectra (XAS spectra). The XAS and XMCD spectra show a characteristic feature of the localized Mn 2+ 3d states. From the analyses of the spectra based on the configuration interaction theory, the parameters such as the p-d hybridization and p-d exchange constant N 0β are estimated.
