通过介电、极化和应变磁滞测量，研究了锆钛酸铅锶 (PSZT) 陶瓷中电场诱导的反铁电 (AFE) 到铁电 (FE) 的相变。制备了具有不同锶和Zr/Ti比率的PSZT组合物，其位于铁电相区、反铁电相区以及AFE/FE相界附近。测量不同组合物的介电性能作为温度的函数。 AFE-FE 相变和磁滞所需的电场受温度和成分的影响。还测量并讨论了相变过程中的熵变和场引起的应变。
The electric field-induced antiferroelectric (AFE) to ferroelectric (FE) phase transition in lead strontium zirconate titanate (PSZT) ceramics was studied by means of dielectric, polarization, and strain hysteresis measurements. PSZT compositions with varying strontium and Zr/Ti ratio, located in the ferroelectric, antiferroelectric phase regions, and near the AFE/FE phase boundary were prepared. Dielectric properties were measured as a function of temperature for different compositions. The electric field required for AFE–FE phase transition and hysteresis were affected by the temperature and composition. The entropy change during phase transition and the field-induced strain were also measured and discussed.
