| The effect of correlation-driven electronic transitions are described for the V2O3, NiS2-xSex, and Fe3O4 systems. The various tranformations can all be rationalized in terms of elementary concepts pertaining to the Mott-Hubbard intraatomic electronic interactions or in terms of an order-disorder formalism involving Coulomb interactions among electrons on adjacent sites. Attention is directed to some outstanding issues that require further resolution. |
