Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201305932-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>An extension in magnetoelectric effects</bold> is proposed to include reversible chemistry‐controlled magnetization variations. This ion‐intercalation‐driven magnetic control can be fully reversible and pertinent to bulk material volumes. The concept is demonstrated for ferromagnetic iron oxide where the intercalated lithium ions cause valence change and partial redistribution of Fe³⁺ cations yielding a large and fully reversible change in magnetization at room temperature. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pghrq65t89" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
