Abstract

Electrical control of magnetic properties is crucial for device applications in the field of spintronics. We demonstrated the electrical control of the ferromagnetic phase transition at room temperature in cobalt, a representative of the transition-metal ferromagnetic family. Solid-state field effect devices, consisting of an ultra-thin cobalt film covered by a dielectric layer and a gate-electrode on top of that, were fabricated for this experiment. We found that the ferromagnetic state of the film could be turned on and off isothermally and reversed simply by applying a gate voltage between the cobalt layer and the gate electrode.
