Ferromagnetic EuS films: Magnetic stability, electronic structure and magnetic surface states
Wolf Müller, Wolfgang Nolting
We present the temperature and layer dependent electronic structure of a 20-layer EuS(100)-film using a combination of first-principles and model calculation, the latter based on t…
Temperature-dependent quasiparticle band structure of the ferromagnetic semiconductor EuS
W. Mueller, W. Nolting
We present calculations for the temperature-dependent electronic structure of the ferromagnetic semiconductor EuS. A combination of a many-body evaluation of a multiband Kondo-latt…
Kondo-lattice model: Application to the temperature-dependent electronic structure of EuO(100) films
R. Schiller, W. Mueller, W. Nolting
We present calculations for the temperature-dependent electronic structure and magnetic properties of thin ferromagnetic EuO films. The treatment is based on a combination of a mul…
The temperature dependent behaviour of surface states in ferromagnetic semiconductors
R. Schiller, W. Mueller, W. Nolting
We present a model calculation for the temperature dependent behaviour of surface states on a ferromagnetic local-moment film. The film is described within the s-f model featuring…
On the origin of surface states in a correlated local-moment film
R. Schiller, W. Mueller, W. Nolting
The electronic quasiparticle structure of a ferromagnetic local moment film is investigated within the framework of the s-f model. For the special case of a single electron in an o…
