Abstract

Polarization reversals in ferroelectrics in the presence of 90° domain walls are studied using a simplified model. The rotation of a single polarization under the field applied perpendicularly to the original orientation correlates to the anisotropy of local potential energy. The polarization reversals in a ferroelectric system consisting of the a- and the c-domains are studied on the basis of the Landau–Ginzburg free energy. A complex mechanism of polarization reversal was found to depend strongly on the spatial anisotropy of the Landau–Ginzburg energy.
