Temperature-dependent surface state and magnetization of thin ferromagnetic EuS films — •W. Nolting and W. Müller — Lehrstuhl Festkörpertheorie, Institut für Physik, Humboldt-Universität zu Berlin

We present results for the temperature- and layer-dependent electronic structure of thin ferromagnetic EuS (100) films. A combination of a many-body evaluation of a multiband Kondo-lattice model and a first-principles band structure calculation (TB-LMTO) is used to get as realistically as possible temperature- and correlation effects. The calculated layer dependent magnetization shows a good agreement with the experiment. The results are discussed in terms of spectral densities, densities of states and band-structures. Special attention is devoted to the appearance of magnetic 5d-surface states.
