| Popis: | This study provides a theoretical method to calculate x-ray magnetic circularly polarized emission spectra at the K${}_{\ensuremath{\alpha}}$ transitions in transition-metal ferromagnets. The method is applied to metallic iron. It reproduces the observed tail structures which originate from the electron excitations on the correlated $d$ bands. Cosinusoidal emission angle dependence of the spectral intensity enables one to elucidate the magnetization directions deep inside of bulk ferromagnets. |
