It is proven that the sum rules for X-ray magnetic dichroism (XMCD) spectra that are used to separate spin and orbital contributions to the magnetic moment are formally correct for an arbitrary strength of electron-electron interactions. However, their practical application for strongly correlated ...
X-ray absorption spectraspin renormalization techniquesum rule correctionDistinguishable L2 and L3 edges and a clear separation into j 3/2 and j 1/2 excitations are necessary for the application of L2,3 edge X-ray magnetic circular dichroism (XMCD) sum rules, which provide element-specific ...
It is found that the XMCD sum rules are fully satisfied in the framework of the crystal-field multiplet approach resulting from the very general arguments developed in their derivations by Thole and Carra. Analytical expressions for the orbital magnetic moment [L(z)], the spin magnetic moment [...

We find agreement within experimental errors between the two magnetometry measurements, confirming that the XMCD sum rules are applicable to this strained low-symmetric system.doi:10.1088/0953-8984/9/9/005Lee, JaeyongLauhoff, GFermon, CHope, S...

A recent article (Phys. Rev. Lett. 77 (1996) 1508) based on the insights of Theo Thole shows that, in a description in terms of inelastic scattering, the XMCD absorption sum rules should hold also for fluorescence yield in a large number of important cases. In this paper we give some ...
XMCD sum rules are checked through an analytical calculation of Cu 2+ L 2,3 edge. The sum rules are analytically satisfied as expected from the very general arguments developed in their derivation by Thole and Carra (1993). Analytical expressions for 〈 L z 〉, 〈 S z 〉 and 〈 T z ...
