Paper Abstract

Some relaxor ferroelectric single crystals undergo a diffuse phase transformation while others undergo a step like transformation when driven by either stress or electric field. In this work the distributed transformation is modeled as a sequence of distributed transformations associated with compositional fluctuations typical or relaxor ferroelectrics. The distribution function is taken to be Gaussian. The results are in good agreement with observations of the response of <011> cut PMN-0.32PT single crystals.
