Bulk and Surface Effects in X-Ray Magnetic Circular Dichroism of Iron Clusters

Abstract

General trends in x-ray magnetic circular dichroism (XMCD) spectra of iron clusters of different sizes are theoretically investigated using the fully-relativistic spin-polarized multiple-scattering formalism. Purely geometrical effects of clustering and cluster-size effects are explored separately from effects of various scattering potentials and/or treatment of the surface barrier. We found that a high portion of non-bulk atoms makes the XMCD spectra of iron clusters to appear significantly different from bulk spectrum, even for quite large clusters. If the vacuum surrounding the cluster is taken into account, XMCD spectra of iron clusters change essentially (in comparison with clusters cut out of the bulk or with clusters embedded in a sea of free electrons).
