Electrical-conductivity and thermoelectric-power measurements of magnetite and iron-aluminate spinels at high temperatures confirm a small-polaron model of electronic conduction. Electrical properties corroborate the previously established cation distribution and defect model. Iron cations become randomly distributed between sublattices at the highest temperature.
