Correlation effects in the valence bands of ferromagnetic semiconductor EuS

We present a many body analysis of the multi‐band 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. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
