MCD in resonant Photoemission at the Gd M_IV,V edge — •Z. Hu, G. van der Laan, K. Starke, and G. Kaindl — Institut für Experimentalphysik, Freie Universität Berlin, Arnimallee 14, 14195 Berlin, Germany

We report on the analysis of multiplet finestructures in the MCD signal of the Gd M_IV,V x-ray absorption spectra (XAS) and in the associate resonant 4d- and 4f-Photoemission(PE) spectra. The experimental resonant 4f-PE spectra are found to be well reproduced by atomic multiplet theory, including minute detailes of the MCD signal of the so-called spin-flip ⁵X states. A comparison with resonant 4f-PE at the Gd N_IV,V edge [1] will be presented.
