Physical Review B 54, pp R15618-R15621 (1996) Magnetic dichroism with unpolarized x rays in angle-resolved photoemission has been systematically investigated for the 2p core levels of Fe, Co, and Ni. In contrast to Fe 2p, we find the dichroism in the Ni 2p spectra to be mainly governed by electronic correlations. The fine structure observed in the Co 2p spectrum indicates a distinct influence of many-body interactions also in this material.
