Abstract

Electrical conductivity in magnetite has been studied experimentally as a function of temperature and oxygen activity between 560 and 1400 degree C. The results indicate that above T//C octahedral site small polaron mechanism is dominant over the entire temperature range. By comparing data on electrical conductivity and thermoelectric power, a second (small polaron) mechanism is detected at elevated temperature.
