Magnetic linear dichroism in angular resolved photoemission of the valence band of 3d metal thin films on W(110) — •Tobias Löffler1, Torsten Veltum1, Mathias Gehlmann2, Sven Döring2, Lukasz Plucinski2, and Mathias Getzlaff11Institut für Angewandte Physik, Heinrich-Heine-Universität Düsseldorf, 40225 Düsseldorf — 2Peter Grünberg Institut PGI-6, Forschungszentrum Jülich, 52428 Jülich

The technique of magnetic linear dichroism in the angular distribution (MLDAD) of photoelectrons allows the study of the electronic band structure as well as the study of magnetic properties of metallic thin films and single crystals. We are interested in a deeper understanding of the magnetic linear dichroism of ferromagnetic 3d metals. Special attention is turned to the question, which parts of the band structure are responsible for this phenomenon. In this study, linearly polarized synchrotron radiation in the VUV regime is used. The investigated system consists of epitaxially grown 3d metal thin films on a W(110) single crystal.

The exciting photon energy is varied to investigate the electronic structure of the valence band. At lower energies, existing dichroism measurements of Co(0001) on W(110) are confirmed [1] and extended to off-normal geometry. To investigate similarities, angle-resolved spectra of Co(0001) and Fe(110) on W(110) are compared.
