Ferromagnetism and temperature-dependent Electronic Structure of hcp Gadolinium
C. Santos, V. Eyert, W. Nolting
We use a combination of a many-body model analysis with an ab initio band structure calculation to derive the temperature dependent electronic quasiparticle structure of the rare-e…
The Correlated Kondo-lattice Model
J. Kienert, C. Santos, W. Nolting
We investigate the ferromagnetic Kondo-lattice model (FKLM) with a correlated conduction band. A moment conserving approach is proposed to determine the electronic self-energy. Map…
Ferromagnetic Kondo-Lattice Model
W. Nolting, W. Müller, C. Santos
We present a many-body approach to the electronic and magnetic properties of the (multiband) Kondo-lattice model with ferromagnetic interband exchange. The coupling between itinera…
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…
Quantum effects in the quasiparticle structure of the ferromagnetic Kondo lattice model
D. Meyer, C. Santos, W. Nolting
A new ``Dynamical Mean-field theory'' based approach for the Kondo lattice model with quantum spins is introduced. The inspection of exactly solvable limiting cases and several kno…
Magnons in the ferromagnetic Kondo-lattice model
M. Vogt, C. Santos, W. Nolting
The magnetic properties of the ferromagnetic Kondo-lattice model (FKLM) are investigated. Starting from an analysis of the magnon spectrum in the spin-wave regime, we examine the f…
