Abstract
Measurements are reported of the thermo-e.m.f. of a thermoelectric junction composed of polycrystalline ferrites or multilayered ferrite films as a function of the temperature. The thermo-e.m.f. of the bulk and ferrite films was much larger than that of the conventional thermoelectric junction made of metals. A positive or negative thermoelectric power was observed depending on the difference in the combination of ferrites. The temperature dependence was almost linear from room temperature up to about 500°C and above which it showed a tendency to saturate. Application of a magnetic field had a reducing effect upon the thermo-e.m.f. at temperature of room to the Curie temperature.
