Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Butterfly magnet</bold>: The replacement of diamagnetic Co^III for Cr^III in a 3d‐4f butterfly complex results in vastly improved single‐molecule magnet properties. Longer relaxation times are found, with magnetic hysteresis observed. This is due to exchange interactions between the Dy^III and Cr^III ions, resulting in a multilevel exchange barrier with significantly reduced quantum tunneling of the magnetization.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4t77rj6q" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
