INVESTIGATION OF THE STOICHIOMETRIC AND STRUCTURAL VARIABLES WHICH AFFECT CONDUCTIVITY IN FERROMAGNETIC CERAMIC MATERIALS FOR USE IN MAGNETIC CIRCUITS.
Abstract
Results of investigations of the electrical resistivity, thermoelectric power, thermal conductivity, optical reflectivity, and absorption as functions of temperature are reported for magnetite and cobalt iron ferrites prepared as high-purity single crystals with controlled stoichiometry. New data are compared with those in the literature. The influence of the magnetic transition on thermal conductivity in the ferrites is deduced by a comparison with data for nonmagnetic spinels. An idealized model for the electrical properties is partially developed from the electrical and optical results. (Author)
