Abstract

The composition dependence of thermoelectric power (Seebeck coefficient) in ferrospinels with fixed valence foreign cations has been calculated via combined small polaron and cation distribution models. Satisfactory agreement with experimental data is achieved assuming cation distribution thermodynamic constants to be independent of foreign cation concentration. Data are analyzed for a trivalent foreign cation (Al³⁺) at elevated temperature and for divalent foreign cations (Ni²⁺, Mg²⁺, Zn²⁺) at lower temperatures.
