Abstract:
A magnetic device may include a layer stack. The layer stack may include a first ferromagnetic layer; a non-magnetic spacer layer on the first ferromagnetic layer, where the non-magnetic spacer layer comprises at least one of Ru, Ir, Ta, Cr, W, Mo, Re, Hf, Zr, or V; a second ferromagnetic layer on the non-magnetic spacer layer; and an oxide layer on the second ferromagnetic 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 or a current. A thickness and composition of the non-magnetic spacer layer may be selected to enable a switching direction of the magnetic orientation of the second ferromagnetic layer to be controlled by a sign of the bias voltage.

Claim (Index 10):
A method comprising:\n controlling, by a write controller, a voltage source to output a positive bias voltage across a layer stack, wherein the layer stack comprises:\n a first ferromagnetic layer; \n a non-magnetic spacer layer on the first ferromagnetic layer, wherein the non-magnetic spacer layer comprises at least one of Ru, Ir, Ta, Cr, W, Mo, Re, Hf, Zr or V; \n a second ferromagnetic layer on the non-magnetic spacer layer; \n an oxide layer on the second ferromagnetic layer, wherein the positive bias voltage causes switching of a magnetic orientation of the second ferromagnetic layer from a first direction to a second direction without application of an external magnetic field or a current; and \n controlling, by the write controller, the voltage source to output a negative bias voltage across the layer stack, wherein the negative bias voltage causes switching of the magnetic orientation of the second ferromagnetic layer from the second direction to the first direction without application of an external magnetic field or a current.
