ABSTRACT This article presents the effect of processing parameters on the ferroelectric hysteresis behavior of [(1-x)Ba0.9Ca0.1TiO3-x(BaSn0.2Ti0.8O3)] ceramics for x = 0, 0.4, 0.45, 0.5 and 0.6 samples. The ferroelectric hysteresis scaling relations for coercive field (Ec) and remnant polarization (Pr) in the form of temperature have been proposed. The power law temperature exponents based on scaling were systematically established for the hysteresis parameters. The temperature dependent scaling of Ec and Pr at sintering temperature of 1480°C for 5 hr yields Ec α T−0.42, Ec α T−0.32, Ec α T−0.35 and Ec α T−0.34 and Pr α T−2.20, Pr α T−2.07,Pr α T−2.09 and Pr α T−2.12 respectively. Further, to analyze the domain dynamics, back switching polarization (Pbc) in terms of temperature (T) was also estimated by Arrhenius law and the average activation energy was evaluated. The maximum activation energy for domain switching is found to be 0.199 eV at 17 kV/cm for x = 0.6 sample.

[(1-x)Ba0.9Ca0.1TiO3-x(BaSn0.2Ti0.8O3)]陶瓷铁电磁滞参数的温度相关动态磁滞缩放

摘要 本文介绍了加工参数对 [(1-x)Ba0.9Ca0.1TiO3-x(BaSn0.2Ti0.8O3)] 陶瓷的铁电滞后行为的影响，用于 x = 0、0.4、0.45、0.5 和 0.6 样品. 已经提出了矫顽场 (Ec) 和剩余极化 (Pr) 的铁电磁滞标度关系，以温度形式表示。系统地为滞后参数建立了基于缩放的幂律温度指数。Ec 和 Pr 在 1480°C 烧结温度下 5 小时的温度相关缩放产生 Ec α T-0.42、Ec α T-0.32、Ec α T-0.35 和 Ec α T-0.34 和 Pr α T-2.20、Pr分别为α T-2.07、Pr α T-2.09 和Pr α T-2.12。此外，为了分析领域动态，还通过阿伦尼乌斯定律估计了温度 (T) 方面的反向转换极化 (Pbc)，并评估了平均活化能。对于 x = 0.6 样品，域切换的最大活化能在 17 kV/cm 下为 0.199 eV。
