摘要：

A general formulation of linear and circular dichroism in the absorption of x rays in magnetically ordered systems is presented. The processes which induce sensitivity to magnetic properties are discussed. We demonstrate that the usually neglected electric quadrupole transitions can be as important as the dipole terms for the interpretation of magnetic dichroism experiments on transition metals and rare earths. © 1990 The American Physical Society.
