摘要：

Thermal conductivity of a single-crystal lead magnesium niobate titanate-(1-x)Pb(Mg1/3Nb2/3)O-3-xPbTiO(3) with x=0.34 has been studied at temperatures from 20 to 320 K and in an applied electric field. The thermal conductivity of the crystal is similar to that of a typical amorphous solid both in the temperature dependence and in magnitude. The electric field dependence of the thermal conductivity and strain show an abrupt change at about 15 kV/cm, which is interpreted as due to a field-induced phase transformation in the crystal.
