摘要：

We present a calculation of magnetic circular dichroism in 3d and 4d core X-ray absorption spectra of rare earth systems assuming that a trivalent rare earth ion is placed in an infinitesimal uniform magnetic field. The calculation covers all rare earth elements between Ce and Tm. Features of the dichroism are explained by elementary considerations of transition matrix of a polarized light, spin-orbit coupling of a core hole, and exchange interaction between a core hole and a 4f electron. © 1990, THE PHYSICAL SOCIETY OF JAPAN.
