Self-energy approach to the correlated Kondo-lattice model
W. Nolting, G. G. Reddy, A. Ramakanth +2
We develop an interpolating self-energy approach to the correlated Kondo-lattice model. The correlation of the band electrons is taken into account by a Hubbard interaction. The me…
Local Density of States in the Antiferromagnetic and Ferromagnetic Kondo Models
P. Sinjukow, D. Meyer, W. Nolting
Based on a simple approximation scheme we have computed the local density of states (LDOS) of the antiferromagnetic and ferromagnetic Kondo models for the full range of band occupa…
Influence of Spin Wave Excitations on the Ferromagnetic Phase Diagram in the Hubbard-Model
W. Rumsch und W. Nolting
The subject of the present paper is the theoretical description of collective electronic excitations, i.e. spin waves, in the Hubbard-model. Starting with the widely used Random-Ph…
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…
Ferromagnetism in the Kondo-lattice model
C. Santos, W. Nolting
We propose a modified RKKY-technique to evaluate the magnetic properties of the ferromagnetic Kondo-lattice model. Together with a previously developed selfenergy approach to the c…
Temperature-dependent electronic structure and magnetic stability of thin ferromagnetic films
W. Nolting, C. Santos
We study correlation effects and temperature dependencies in the electronic structure of thin ferromagnetic local-moment films. In a first step the Kondo-lattice model is investiga…
