INVESTIGATION OF THE STOICHIOMETRIC AND STRUCTURAL VARIABLES WHICH AFFECT CONDUCTIVITY IN FERROMAGNETIC CERAMIC MATERIALS FOR USE IN MAGNETIC CIRCUITS

Abstract

AD-260 9884N2nd transmission of magnetite. Resistivity and thermoelectric power as a function of temperature are reported for magnetite. Hall effect studies are inconclusive. Discrepancies between previous data and those obtained are noted. The thermal conductivity of magnetite has been measured as a function of temperature. The room temperatu e value is about 70 milliwatts, and an abrupt change is noted at the 120 K transition. (Author)
