Abstract
The atomic-like behavior of the photoionization cross-section of core level s in solids is remarkably displayed in the observation of linear magnetic d ichroism in the angular distribution of photoelectrons. Structure-related e ffects are clearly visible as modulations of the dichroism signal, induced by photoelectron diffraction, a fact that can be exploited to obtain inform ation from magnetic surfaces. A systematic investigation of such effects ha s been carried out for Fe 2p and 3p core levels on the ALOISA beamline at E LETTRA. We present results for Fe(0 0 1) with a reference calibration for a morphous RCP-Fe grown on Fe30Ni50B20, which provides the atomic-like standa rd, free from diffraction effects.
