Magnetoelectric coupling allows changing the magnetic state of a material by applying an electric field. To date, this phenomenon has mainly been observed in insulating materials. Metallic bulk systems do not exhibit this effect, because applied electric fields are screened by conduction electrons. We have been able to switch the magnetic order in a metallic nanostructure reversibly between two stable magnetic states using magnetoelectric coupling induced by an applied electric field.
