Abstract
This article presents the effect of processing parameters on the ferroelectric hysteresis behavior of Ba0.85Sr0.15Zr0.1Ti0.9O3 (BSZT) ceramics. The ferroelectric hysteresis scaling relations for coercive field (E-c) and remnant polarization (P-r) as a function of temperature have been proposed. The power law temperature exponents based on scaling were systematically established for all the hysteresis parameters. The temperature dependent scaling of E-c and P-r at sintering temperature of 1400, 1425, 1450 and 1475 degrees C yields EcT0.43, EcT0.84, EcT0.50, EcT0.37 and PrT-1.73, PrT-1.55, PrT-1.73, PrT-1.69 respectively. Additionally, the scaling relations for the samples sintered at 1450 degrees C at different time intervals of 3, 4, 5 and 6hrs were also established. Finally, to understand the domain dynamics, back switching polarization (P-bc) as a function of temperature (T) was also estimated by Arrhenius law and the average activation energy was evaluated.
