Abstract
A magnetic tunnel junction is provided. The magnetic tunnel junction comprises an insulating tunnel barrier and a fixed ferromagnet layer adjacent the tunnel barrier. The fixed ferromagnet comprises a fixed magnetization along an easy axis approximately normal to an interface between the fixed ferromagnet and the tunnel barrier. A free ferromagnet layer is adjacent the tunnel barrier on the side opposite the fixed ferromagnet. The free ferromagnet layer comprises a bistable magnetization along the easy axis that can switch between a parallel state and an anti-parallel state with the fixed ferromagnet. A heavy metal layer is adjacent the free ferromagnet on the side opposite the tunnel barrier. A unidirectional electric current pulse through the heavy metal layer switches the bistable magnetization of the free ferromagnet, thereby switching an electrical resistance state of the magnetic tunnel junction.
