Ferromagnetism and Kondo Insulator Behavior in the Disordered Periodic Anderson Model
arXiv:0801.3934 · doi:10.1103/PhysRevLett.100.246401
Abstract
The effect of binary alloy disorder on the ferromagnetic phases of f-electron materials is studied within the periodic Anderson model. We find that disorder in the conduction band can drastically enhance the Curie temperature due to an increase of the local f-moment. The effect may be explained qualitatively and even quantitatively by a simple theoretical ansatz. The emergence of an alloy Kondo insulator at non-integer filling is also pointed out.
