Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201405205-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>180° domain wall motion</bold> in a tetragonal ferroelectric oxide is accelerated by an order of magnitude using in situ strain in a force microscope. Single‐domain PbZr_0.2Ti_0.8O₃ films on piezoelectric (001)‐oriented 0.72PbMg_1/3Nb_2/3O₃‐0.28PbTiO₃ substrates allow for direct investigation of strain‐dependent domain dynamics. The strain effect depends on the sign of applied field through strain‐dependent electrode built‐in potentials and a suggested charging of tilted walls. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj42zdnss" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
