摘要：

A band theoretical study of circular magnetic X-ray dichroism (CMXD) in Fe and Co multilayers [Fe(Co)(2)Cu-6(001), Fe1Cu(Ag, Au)(5)(001), Co2Pd4(111) and Co2Ptm(111) (m = 1, 4, 7)] has been carried out. The orbital magnetic moment given by the CMXD sum rule is found to be too small by up to 50%. Nevertheless, there is a linear relationship between the integrated CMXD signal and the orbital magnetic moment for each ion species. The calculated magnetic dipole moment is small in the Co systems, but is comparable to the orbital magnetic moment in the Fe systems. The CMXD sum rule for spin magnetization is found to give rather accurate spin magnetic moments (errors within 15%) for the Co systems, and also for the Fe systems if the magnetic dipole moment is included.
