Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201402442-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A large enhancement of nanodomain retention</bold> is shown in the mixed‐phase region of a strained BiFeO₃ epitaxial film. The superior ferroelectric retention is attributed to a lower elastic‐energy density at the phase boundaries, which act as periodic pinning centers for the domain wall motion. This study delivers a new pathway of incorporating an elastic‐energy term to assist ferroelectric retention. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh1f8bcsn2" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
