Relaxor ferroelectric PMN-32%PT crystals under stress, electric field and temperature loading: II-33-mode measurements

Paper I [1] reported a phase transition driven by combinations of stress and electric field in < 110 > oriented PMN-32%PT single crystals. In this paper, evidence of multiple phase transitions is reported for < 001 > oriented PMN-32%PT single crystals under combinations of stress, electric field, and temperature loading. The results indicate that the driving force for the transformations decreases with increasing temperature. Material properties for different phases under excursions of electric field and stress are reported. (c) 2005 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
