Abstract
A magnetic device may include a layer stack. The layer stack may include a first ferromagnetic layer; a spacer layer on the first ferromagnetic layer; a second ferromagnetic layer on the spacer layer; and a dielectric barrier layer on the second ferromagnetic layer. In some examples, the layer stack may also include an additional ferromagnetic layer and an additional spacer layer. The magnetic device also may include a voltage source configured to apply a bias voltage across the layer stack to cause switching of a magnetic orientation of the second ferromagnetic layer without application of an external magnetic field.
