Classification: CPC G  H | IPC G  H

Claim 0:
1. A magnetic tunnel junction, comprising:
an insulating tunnel barrier;
a fixed ferromagnet layer adjacent a first side of the insulating tunnel barrier, wherein the fixed ferromagnet layer comprises a fixed magnetization along an easy axis approximately normal to an interface between the fixed ferromagnet and the insulating tunnel barrier;
a free ferromagnet layer adjacent a second side of the insulating tunnel barrier opposite the fixed ferromagnet layer, wherein the free ferromagnet layer comprises a bistable magnetization along the easy axis, wherein the bistable magnetization can switch between a parallel state and an anti-parallel state with the fixed magnetization of the fixed ferromagnet layer; and
a heavy metal layer on a side of the free ferromagnet layer opposite the insulating tunnel barrier, the heavy metal layer configured to receive unidirectional electric current therethrough and substantially normal to the easy axis, wherein the unidirectional electrical current pulse applied through the heavy metal layer toggles the bistable magnetization of the free ferromagnet layer between the parallel and anti-parallel states regardless of which state the free ferromagnet layer is in upon application of the unidirectional electric current pulse.
