Abstract:

Role of exchange interaction is studied using extended Falicov–Kimball model. A discontinuous valence transition is observed at a critical f-level energy. Transition is sharper for smaller exchange interaction. A double-peak structure in specific heat appears for E < =Ec. For antiferromagnetic type of exchange interaction, a Curie contribution to the susceptibility is observed.
