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…
Ferromagnetism in the Periodic Anderson Model: A Comparison of Spectral Density Approximation (SDA), Modified Alloy Analogy (MAA) and Modified Perturbation Theory (MPT)
D. Meyer, W. Nolting
We compare different approximation schemes for investigating ferromagnetism in the periodic Anderson model. The use of several approximations allows for a detailed analysis of the…
Ferromagnetism in the Periodic Anderson Model - a Modified Alloy Analogy
G G Reddy, D Meyer, S Schwieger +2
We introduce a new aproximation scheme for the periodic Anderson model (PAM). The modified alloy approximation represents an optimum alloy approximation for the strong coupling lim…
Dynamical mean-field study of ferromagnetism in the periodic Anderson model
D. Meyer, W. Nolting
The ferromagnetic phase diagram of the periodic Anderson model is calculated using dynamical mean-field theory in combination with the modified perturbation theory. Concentrating o…
Kondo screening and exhaustion in the periodic Anderson model
D. Meyer, W. Nolting
We investigate the paramagnetic periodic Anderson model using the dynamical mean-field theory in combination with the modified perturbation theory which interpolates between the we…
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…
