ABSTRACT
It is demonstrated that the magnetic circular dichroism in x-ray absorption (XMCD) can be used to probe the spin and orbital high-field susceptibilities of spontaneously magnetic solids on the basis of the so-called XMCD sum rules. A corresponding theoretical description is presented that is formulated in terms of the fully relativistic multiple scattering Green's function formalism. Examples for the field-induced changes in XMCD spectra are given together with an application of the sum rules to these spectra that demonstrates their relation to the high-field susceptibility.
