Angular Dependence of Magnetic Dichroism in 4f-Photoemission — •S. Gorovikov, S. Bode, K. Starke, and G. Kaindl — Institut für Experimentalphysik, Freie Universität Berlin, Arnimallee 14, 14195 Berlin, Germany


The applikation of Magnetic Dichroism in core-level Photoemission (MDPE) as magnetometer has been restricted to the detection of relative magnetization changes[1]. At the example of Gd(0001) 4f-PE line and circular-light excitation we have investigated the dependence of MCD signal on the electron emission direction. We observe drastic changes which are explained by photoelectron diffraction influences on the top of the expected angular variation in the atomic limit[2].
