Correlation effects in the valence bands of EuS — •Anand Sharma and Wolfgang Nolting — Lehrstuhl Festkoerpertheorie, Institut fuer Physik, Humboldt-Universitaet zu Berlin, Newtonstr.15, 12489, Berlin, Germany.

We present a many body analysis of the multiband Kondo lattice model. The study is then combined with the first principles TB-LMTO band structure calculations, in order to investigate the temperature dependent correlation effects in the 3p valence bands of the ferromagnetic semiconductor,EuS. Some of the physical properties of interest like the quasi-particle density of states (Q-DOS), spectral density (SD) and quasi-particle band structure (Q-BS) are calculated and discussed. Therewith, we propose a spin resolved ARPES of the valence bands of EuS to be performed.
