Spin- and orbital-polarized multiple-scattering theory of magneto-x-ray effects in Fe, Co, and Ni
- Daresbury Laboratory, Warrington, Cheshire WA4 4AD (United Kingdom)
Systematic theoretical studies of various magneto-x-ray effects (Faraday rotation, resonant magnetic x-ray scattering as well as magnetic circular dichroism) at the K and L{sub 2,3} edges in bcc Fe, fcc, and hcp Co, and fcc Ni have been carried out. Spin- and orbital-polarized multiple-scattering theory is used. It is found that the orbital polarization (correction) significantly increases the orbital moment and the magnitude of the K magnetic circular dichroism and Faraday rotation spectra which are then in reasonable agreement with available experiments. On the other hand, the orbital polarization only slightly affects the spin magnetic moment of all the systems studied and the L{sub 2,3} magneto-x-ray spectra of Fe and Co. There is an overall agreement in the L{sub 2,3} magneto-x-ray spectra between the theory and the experiments. However, some differences between the theoretical and experimental magneto-x-ray spectra in between the L{sub 3} and L{sub 2} edges exist especially in Fe and Ni, indicating that one-electron theory is not fully adequate. The fundamental relations between the different magneto-x-ray spectra are emphasized. {copyright} {ital 1997} {ital The American Physical Society}
