Abstract The time dependence behavior of the dielectric permittivity of lead lanthanum zirconate titanate transparent ceramic sample from the moment of the field application at certain temperatures after the zero-field cooled regime is compared to that exhibited by a single-crystal lead magnoniobate. The delay time of the phase transition from the glasslike to the field-induced ferroelectric state was determined from the sharp change in the dielectric permittivity in a lead magnoniobate single crystal. The same transition in lead lanthanum zirconate titanate has more smooth behavior. In the case of ultraviolet illumination, the delay becomes a few times shorter for both cases.

弛豫中相变到极性相的延迟：紫外线照射的影响

摘要 将锆钛酸铅镧透明陶瓷样品在零场冷却后的特定温度下从现场应用那一刻起的介电常数随时间变化的行为与单晶镁铌酸铅所表现出的行为进行了比较。从玻璃态到场诱导铁电态的相变延迟时间是根据镁铌酸铅单晶中介电常数的急剧变化确定的。锆钛酸镧铅的相同过渡具有更平滑的行为。在紫外线照射的情况下，两种情况的延迟都会缩短几倍。
