Abstract
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.
本文研究了在x = 0、0.4、0.45、0.5和0.6样品下，工艺参数对[(1-x)Ba0.9Ca0.1TiO3-x(BaSn0.2Ti0.8O3)]陶瓷铁电迟滞行为的影响。提出了矫顽力场(Ec)和残余极化(Pr)的铁电迟滞以温度为标度关系。系统地建立了基于标度的滞后参数幂律温度指数。在1480℃烧结5 h时，Ec和Pr的结垢率分别为Ec α T - 0.42、Ec α T - 0.32、Ec α T - 0.35和Ec α T - 0.34,Pr α T - 2.20、Pr α T - 2.07、Pr α T - 2.09和Pr α T - 2.12。在此基础上，利用Arrhenius定律估计了温度(T)下的反向开关极化(Pbc)，并计算了平均活化能。在17 kV/cm下，x = 0.6样品的畴切换激活能最大为0.199 eV。
