Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201501636-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>An optical probe</bold> of the ferroelectric domain distribution and manipulation in BiFeO₃ thin films is reported using optical second harmonic generation. A unique relation between the domain distribution and its integral symmetry is established. The ferroelectric signature is even resolved when the film is covered by a top electrode. The effect of voltage‐induced ferroelectric switching is imaged. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj2h30rmnn" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
