Abstract
Ferroelectric phase inducing threshold electric field Eth and its temperature dependence were determined in relaxor ferroelectric 0.87Pb(Mg₁/₃Nb₂/₃)O₃-0.13PbTiO₃ (PMN-13PT) ceramics by measuring dielectric response on a dc field pulse. Evolution of the induced ferroelectricity was observed by means of polarization measurements. An inducing threshold field was found to have a minimum of Eth,min = 1.55 kV/cm at T = −5 °C. In contrast to pure PMN, which shows a minimum threshold field near the depolarization temperature, the temperature of the minimum threshold field differs by an amount of ΔT = 23 °C from the depolarization temperature Tdp = 18 °C in PMN-13PT.
