摘要：
Theoretical study is made, with an extended single impurity Anderson model, for the spectra of X-ray magnetic circular dichroism (XMCD) at Ce L-2,L-3 edges of trivalence, weakly mixed valence and strongly mixed valence Ce compounds under external magnetic field. Recent experimental results for CePd3 are well explained. The present theory gives a framework to understand a variety of XMCD behavior of various kinds of ferromagnetic Ce compounds in a unified fashion.
