Intermediate-valence effects on the phase diagram of NiS2-xSex
Abstract
Using a modified Falicov-Kimball model and introducing intermediate valence effects, we reproduce the phase diagram (T-x) of NiS2-xSex. This allows us to develop a simple picture of the physical properties of these compounds based on the concepts proposed to explain the anomalies found in some rare-earth compounds.
