Our results show that PMN-PT compositions near the MPB exhibit phase-transition dynamics that differ markedly from those far below the MPB. We demonstrate that electric-field history significantly affects the field-induced transition temperature Tc, zero-field-cooling (ZFC) delay time tau_ZFC, and induced polarization Pc gained or lost during the transitio"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"PMN-PT compositions near the MPB exhibit phase-transition dynamics that differ markedly from those far below the MPB.
