Theoretical calculation on x-ray magnetic circularly polarized emission for ferromagnetic 3d transition metals Fe, Co and Ni

In this study, we calculate x-ray magnetic circularly polarized emission (XMCPE) spectra at Kα transition for ferromagnetic 3d transition metals (TMs), specifically Fe(bcc), Ni(fcc), and Co(hcp). We obtain XMCPE spectra which agree well with the experiment for Fe. Electron excitations on the 3d bands affect significantly, moderately, and little the difference spectra for Fe, Co, and Ni, respectively. This difference arises from that in the number of d electron in unit cell, and the width of d bands.Asia-Pacific Conference on Condensed Matter Physics 202
