Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201303329-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Charge and polarization modulations</bold> in Fe₃O₄ are controlled by taking advantage of interfacial strain effects. The feasibility of oxidation state control by strain modification is demonstrated and it is shown that this approach offers a stable configuration at room temperature. Direct evidence of how a local strain field changes the atomic coordination and introduces atomic displacements leading to polarization of Fe ions is presented. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4sm3gqtr" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
