Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201502072-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Giant magnetically induced twin variant reorientation</bold>, comparable in intensity with bulk single crystals, is obtained in epitaxial magnetic shape‐memory thin films. It is found to be tunable in intensity and spatial response by the fine control of microstructural patterns at the nanoscopic and microscopic scales. A thorough experimental study (including electron holography) allows a multiscale comprehension of the phenomenon. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj2frx6vp9" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
