| 内容記述 | In x-ray magnetic circularly polarized emission (XMCPE), circularly polarized characteristic x-rays are emitted from a magnetized material.In this study, we develop a theoretical method of calculating XMCPE spectra, considering multiple electron-hole pair excitations within the self-consistent perturbation theory (SCPT), and thereby calculate the XMCPE spectra specifically for ferromagnetic Fe (bcc), Co (hcp), and Ni (fcc).In a comparison of the SCPT results with previous results calculated within the Born approximation, the XMCPE spectra for SCPT are clearly broader in the low-energy side of the $K\alpha$ peaks than that for the Born calculation.The results show that the multiple electron-hole pair excitations play a significant role in x-ray emission processes. | |||||||||
