Abstract

Domain structure of BiFeO₃ thin films can be controlled by adjusting the target composition or the substrate temperature during pulsed laser deposition. Decreasing Bi content in the target or increasing substrate temperature changes the domain structure of BiFeO₃ from 71° to 109°. We suggest that a combination of interface effect and defect induced internal field causes this evolution. © 2012 Copyright 2012 Author(s).
