Template‐Directed FeCo Nanoshells on AuCu

Schematic AuCu/FeCo core–shell magnetic nanoparticles: FeCo shell is precisely synthesized on non-magnetic AuCu core to form the core/shell nanostructures. Due to the non-magnetic AuCu core, the FeCo shell exhibits a transition from single domain to magnetic vortex state.
