合成了一系列新型极性铁电 Aurivilius 氧化物，其 B 位含有 Sc3+。通过介电测量获得的铁电到顺电相变温度 (Tc) 范围为 270−400 °C。对大块样品的极化与电场测量表明，剩余极化范围为 10−12 μC/cm2，比母体 Bi2SrTa2O9 高两倍。
A novel series of polar ferroelectric Aurivillius oxides, containing Sc3+ in the B-site, were synthesized. The ferroelectric to paraelectric phase transition temperature (Tc) obtained from dielectric measurements range from 270−400 °C. Polarization vs electric field measurements on bulk samples revealed that remanent polarizations range from 10−12 μC/cm2, which are two times higher than that of the parent Bi2SrTa2O9.
