摘要：

The temperature dependence of the electrical conductivity of magnetite was measured under hydrostatic pressure up to 18.4 kbar. It is found that the temperature of the conductivity maximum in the high temperature phase is more rapidly reduced by pressure (dTm/dP = -4.1 K/kbar) than the Verwey temperature (dTv/dP = -0.27 K/kbar). The discontinuous change of the conductivity at Tv appears to increase with applied pressure as a result of a lowering of Tm.
