Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201370249-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A complex phase coexistence forms in epitaxial films of BiFeO₃ due to the effects of epitaxial strain and temperature‐induced stresses. The work by H. M. Christen and co‐workers on page 5561 shows that the stripe patterns that form upon cooling of these atomically flat layers are a prerequisite for piezoelectric switching, i.e., the phase coexistence enables the functionality of the material. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg3srrchqc" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
