A Critical Analysis of the Mean-Field Approximation for the Calculation of the Magnetic Moment in the Friedel-Anderson Impurity Model
Gerd Bergmann
It is shown that the calculation of the magnetic moment of a Friedel-Anderson impurity in mean-field theory is unreliable. A class of approximate solutions, which contains the mean…
Quantitative Simulation of the Superconducting Proximity Effect
Gerd Bergmann
A numerical method is developed to calculate the transition temperature of double or multi-layers consisting of films of super- and normal conductors. The approach is based on a dy…
The Conductance of a Perfect Thin Film with Diffuse Surface Scattering
Gerd Bergmann
The conductance of thin films with diffusive surface scattering was solved semi-classically by Fuchs and Sondheimer. However, when the intrinsic electron mean free path is very lar…
The anomalous Hall effect in ferromagnetic Fe: Skew scattering or side jump?
Gerd Bergmann, Manjiang Zhang
The question is investigated whether the anomalous Hall effect (AHE) in Fe films is due to skew scattering or side jump. For this purpose sandwiches of FeIn are investigated in whi…
