Theory of Spin-Resolved Auger-Electron Spectroscopy from Ferromagnetic 3d-Transition Metals
T. Wegner, M. Potthoff, W. Nolting
CVV Auger electron spectra are calculated for a multi-band Hubbard model including correlations among the valence electrons as well as correlations between core and valence electro…
Relativistic photoemission theory for general nonlocal potentials
C. Meyer, M. Potthoff, W. Nolting +2
An improved formulation of the one-step model of photoemission from crystal surfaces is proposed which overcomes different limitations of the original theory. Considering the resul…
Influence of uncorrelated overlayers on the magnetism in thin itinerant-electron films
J. H. Wu, T. Herrmann, W. Nolting
The influence of uncorrelated (nonmagnetic) overlayers on the magnetic properties of thin itinerant-electron films is investigated within the single-band Hubbard model. The Coulomb…
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…
The asymmetric single-impurity Anderson model - the modified perturbation theory
D. Meyer, T. Wegner, M. Potthoff +1
We investigate the single-impurity Anderson model by means of the recently introduced modified perturbation theory. This approximation scheme yields reasonable results away from th…
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…
