Abstract
The thermopower (TEP) and electrical resistance of stoichiometric Fe3O4 crystals have been measured up to pressures of 6 GPa over the temperature range of 80-160 K. The resistance decreases markedly with increasing pressure below the Verwey transition temperature TV and TV decreases linearly with increasing pressure. The magnitude of the TEP as well as the discontinuity at TV decrease with increasing pressure. The thermopower of Fe3O4 shows an interesting upswing at low temperatures (<100 K) which is affected significantly by pressure.
