Relation between L2,3 XMCD and the magnetic ground-state properties for the early 3d element V -: art. no. 184401

State-of-the-art x-ray magnetic circular dichroism measurements of V at the L-2,L-3 edges with an excellent signal-to-noise ratio are analyzed for a Fe0.9V0.1 disordered alloy and a Fe/V-3/Fe(110) trilayer which were prepared in UHV and measured in situ on a Cu(100) single crystal. The absorption fine structure and the magnetic dichroism are discussed in detail with the help of ab initio theory. Several approaches known from literature to obtain magnetic ground-state properties from experimental spectra are tested for their validity.
