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…
Prediction of a surface state and a related surface insulator-metal transition for the (100) surface of stochiometric EuO
R. Schiller, W. Nolting
We calculate the temperature and layer-dependent electronic structure of a 20-layer EuO(100)-film using a combination of first-principles and model calculation based on the ferroma…
Temperature-dependent bandstructure of bulk EuO
R. Schiller, W. Nolting
We present calculations for the temperature-dependent electronic structure of bulk ferromagnetic EuO based on a parametrization of the d-f model Hamiltonian using results of first-…
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…
The temperature dependent bandstructure of a ferromagnetic semiconductor film
R. Schiller, W. Nolting
The electronic quasiparticle spectrum of a ferromagnetic film is investigated within the framework of the s-f model. Starting from the exact solvable case of a single electron in a…
Thickness dependent Curie temperatures of ferromagnetic Heisenberg films
R. Schiller, W. Nolting
We develop a procedure for calculating the magnetic properties of a ferromagnetic Heisenberg film with single-ion anisotropy which is valid for arbitrary spin and film thickness. A…
