摘要：

The resistivity and thermopower of the system Fe3O4-x, Fx (0≤x≤0·15) have been measured in the temperature range 20 to 300 K. A sharp Verwey transition occurs in the concentration range 0≤x≤0·05 and a thermal hysteresis is observed in both the resistivity and thermopower at the transition. At the lowest temperatures a T-1/4 law in the conductivity and the behaviour of the thermopower are attributed to the onset of impurity conduction. Measurements on samples in the concentration range 0·05≤x≤0·15, which do not show a sharp Verwey transition, are interpreted in terms of hopping between ‘ Anderson-localized ' states. © 1979 Taylor and Francis Ltd.
