Abstract

The Mössbauer determined cation distributions of FeV2O4, FeCr2O4, FeMn2O4, Fe3O4, FeCo2O4, CoV2O4, CoCr2O4, CoMn2O4, CoFe2O4 and Co3O4 are compared with the quantitative d-orbital stablization energies of McClure and of Dunitz and Orgel. They are also compared with the qualitative ligand field stabilization energies of Cotton. These theories do not account for observation in the cases of FeMn2O4, FeCo2O4 and CoFe2O4.
