Band model for the understanding of ferromagnetism in semiconductors and insulators
Mirek Hänsel, Wolfgang Nolting, Michael Potthoff
To investigate ferromagnetic semiconductors and insulators, such as the famous EuO, EuS, or CrBr, we propose a hybridized Kondo-lattice model, where, in addition to the conduct…
Exact results on the Kondo-lattice magnetic polaron
S. Henning, P. Herrmann, W. Nolting
In this work we revise the theory of one electron in a ferromagnetically saturated local moment system interacting via a Kondo-like exchange interaction. The complete eigenstates f…
Ferromagnetism and non-local correlations in the Hubbard model
Sören Henning, Wolfgang Nolting
We study the possibility and stability of band-ferromagnetism in the single-band Hubbard model for the simple cubic (SC) lattice. A non-local self-energy is derived within a modifi…
Carrier mediated interlayer exchange, ground state phase diagrams and transition temperatures of magnetic thin films
M. Stier, W. Nolting
We investigate the influence of the carrier density and other parameters on the interlayer exchange in magnetic thin film systems. The system consists of ferromagnetic and non-magn…
The ground state phase diagram of the diluted ferromagnetic Kondo-lattice model
M. Stier, S. Henning, W. Nolting
We investigate the existence of several (anti-)ferromagnetic phases in the diluted ferromagnetic Kondo-lattice model, i.e. ferromagnetic coupling of local moment and electron spin.…
Curie temperatures of the concentrated and diluted Kondo-lattice model as a possible candidate to describe magnetic semiconductors and metals
M. Stier, W. Nolting
We present a theory to model carrier mediated ferromagnetism in concentrated or diluted local moment systems. The electronic subsystem of the Kondo lattice model is described by a…
