Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201405811-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Electrical control of the exchange spring</bold> in antiferromagnetic metals is obtained in [Co/Pt]/IrMn Hall devices by using an ionic liquid, where the exchange spring could transfer the "force" and enable a deeper modulation depth in the IrMn. This work provides a new approach toward electrical modulation of the spin structures in metallic antiferromagnets, which should be significant in advancing the development of low‐power‐consumption antiferromagnet (AFM) spintronics. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjnfxc404" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
