Abstract

An electric-field-induced paraelectric cubic to ferroelectric tetragonal phase transformation has been directly observed in prototypical polycrystalline BaTiO3 at temperatures above the Curie point (T-C) using in situ high-energy synchrotron X-ray diffraction. The transformation persisted to a maximum temperature of 4 degrees C above T-C. The nature of the observed field-induced transformation and the resulting development of domain texture within the induced phase were dependent on the proximity to the transition temperature, corresponding well to previous macroscopic measurements. The transition electric field increased with increasing temperature above T-C, while the magnitude of the resultant tetragonal domain texture at the maximum electric field (4 kV mm(-1)) decreased at higher temperatures. These results provide insights into the phase transformation behavior of a prototypical ferroelectric and have important implications for the development of future large-strain phase-change actuator materials.
