摘　　要：Dielectric,hysteresis(P–E)loops and TSDC properties of transparent 85PZN–15BT ceramic over
150–150℃ were investigated.The sample was found to exhibit a strong relaxor behavior and a relatively small remanent polarization.TSDC studies showed that there existed an electric field-dependent peak in the p versus T.Such interesting features were attributed to the electric field-induced transition and coexistence of polar nanoregion,long-range ordered polar region and nonpolarizable BZN-rich region.
