Abstract
In this paper we study on the effects of heat generated from a moving domain boundary during polarization reversals in ferroelectrics. According to the one-dimensional model of ferroelectrics proposed by Kim (1999), there are two heat sources associated with a moving domain boundary: one is from dissipation mechanisms on the domain boundary and the other from the entropy difference between two variants across the domain boundary. In order to investigate the effects of heat generation and transfer during polarization reversals we utilize the finite difference algorithm shown in Kim and Abeyaratne (1995). The results of calculation show that it is possible for the specimen temperature to reach as high temperatures as observed in experiments.
