摘要：

X-ray magnetic-circular-dichroism (MCD) spectra are calculated using the thin film full potential linearized augmented plane wave energy band method for transition metal surfaces. Together with a model analysis, a clear physical insight is provided for this new and exciting phenomenon. The MCD sum rule for the orbital moments originally derived from a single ion model are found to be valid to within 5-10% even in the band approach which treats the strongly hybridized multiband structure. However, the spin sum rule may result in a larger error due to the effects of s,p-d hybridization. In addition, the magnetic dipole term is very important in the spin sum rule, especially for atoms with lower local symmetry.
