Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201301688-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The highly anisotropic electrocaloric effect, evidenced by both direct measurements</bold> and a descriptive theoretical model in lead‐free relaxor ferroelectric Sr_0.75Ba_0.25Nb₂O₆ single crystals, can be exploited by producing low‐cost grain‐oriented ceramics. Combined with the broad‐temperature‐range cooling regime provided by their polar nanoregions, these materials may be the key to future cost‐ and energy‐efficient solid‐state refrigeration. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pghmfn5cj4" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
