Ferroelastic Domain Boundary-Based Multiferroicity

Abstract

Domain boundary engineering endeavors to develop materials that contain localized functionalities inside domain walls, which do not exist in the bulk. Here we review multiferroic devices that are based on ferroelectricity inside ferroelastic domain boundaries. The discovery of polarity in CaTiO3 and SrTiO3 leads to new directions to produce complex domain patterns as templates for ferroic devices.
