Abstract
A defect/electrical conduction model based upon a mixture of 5:2 and 13:4 (vacancy-to-tetrahedral) clusters is proposed for FeO which is consistent with available diffraction, nonstoichiometry and electrical data. Conduction occurs via small polaron hopping between Fe3+ and Fe2+ on octahedral near-cluster sites with two vacancy nearest neighbors. Evidence is cited for an increase in Fe2+ on tetrahedral (interstitial) sites as temperature increases.
