Abstract

A time-dependent phase field model was utilized to investigate the electric field induced tetragonal-to-orthorhombic (T→O) planar phase transformations of perovskite materials, indicated by the simulated semi-discontinuous polarization-electric field hysteresis. Simulations show that transformations are sensitive to the crystallographic orientation of the applied electric field, the energy threshold for 90° domain switching and the rotation path between tetragonal variants. This indicates that the field induced phase transformation behavior has a significant influence on the evaluation and validation of the Landau coefficients.
