Abstract
Thermoelectric power studies of cobalt substituted copper ferrites of various compositions were investigated from room temperature to well beyond the Curie temperature by the differential method. The Seebeck coefficient is negative for all the compositions showing that these ferrites behave as n-type semiconductors. Plot of Seebeck coefficient versus temperature show a maximum at Curie temperature. On the bases of these results an explanation for the conduction mechanism in Cu–Co mixed ferrites is suggested.
