Interplay of magnetic order and Jahn-Teller distortion in a model with strongly correlated electron system
L. Haritha, G. Gangadhar Reddy, A. Ramakanth +2
The Hubbard model has been employed successfully to understand many aspects of correlation driven physical properties, in particular, the magnetic order in itenerant electron syste…
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…
Low density approach to the Kondo-lattice model
W. Nolting, G. G. Reddy, A. Ramakanth +1
We propose a new approach to the (ferromagnetic) Kondo-lattice model in the low density region, where the model is thought to give a reasonable frame work for manganites with perov…
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…
Ferromagnetism within the periodic Anderson model: A new approximation scheme
D. Meyer, W. Nolting, G. G. Reddy +1
We introduce a new approach to the periodic Anderson model (PAM) that allows a detailed investigation of the magnetic properties in the Kondo as well as the intermediate valence re…
