Influence of Band and Orbital Degeneracies on Ferromagnetism in the Periodic Anderson Model
Unjong Yu, Krzysztof Byczuk, Dieter Vollhardt
We investigate the influence of degeneracies of the conduction band and the -orbital on the stability of ferromagnetism in the periodic Anderson model. To this end we calculate…
Ferromagnetism and Kondo Insulator Behavior in the Disordered Periodic Anderson Model
Unjong Yu, Krzysztof Byczuk, Dieter Vollhardt
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…
Thermoelectric Power in the Double Exchange Model
Beom Hyun Kim, Unjong Yu, Kyoo Kim +1
Employing the Monte-Carlo method and the exact diagonalization, we have investigated the temperature dependence of the thermoelectric power (TEP) for the double exchange model in t…
