Figure 1. (A) Temperature-dependent dielectric response in the range above 300 K for a <001>- oriented PMN–PT crystal on heating from a poled condition under zero field, and subsequent re-cooling. The insert shows a Vogel-Fulcher fit to the frequency dependence of the dielectric constant in the zero-field cooled measurement. Reproduced with permission[5]. Copyright 2001 AIP Publishing LLC.
