Abstract

The 71° stripe domain patterns of epitaxial BiFeO ₃ thin films are frequently being explored to achieve new functional properties, dissimilar from the BiFeO ₃ bulk properties. We show that in-plane switching and out-of-plane switching of these domains behave very differently. In the in-plane configuration the domains are very stable, whereas in the out-of-plane configuration the domains change their size and patterns, depending on the applied switching voltage frequency.
