Abstract

<abstract abstract-type="main" id="pssr201409470-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A Cu‐based organic–inorganic perovskite framework exhibits high‐temperature ferroelectricity with strong magnetoelectric effects. Both electric field control of magnetization and magnetic field control of polarization are realized. Theoretical calculations suggest that a new mechanism of hybrid improper ferroelectricity arising from the Jahn–Teller distortions of magnetic metal ions and tilting of the organic cations are responsible for the peculiar multiferroic behaviors. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh3gtw5b64" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> <p>A Cu‐based perovskite organic–inorganic framework showing high‐temperature improper ferroelectricity.</p> <p>(© 2015 WILEY‐VCH Verlag GmbH &amp;Co.
