Abstract

A three-terminal device is disclosed having a magnetic tunnel junction (MTJ) and a spin orbit torque (SOT) generating layer. The MTJ has a first magnetic layer, a tunnel barrier layer underlying the first magnetic layer, and a second magnetic layer underlying the tunnel barrier, wherein the SOT generating layer is directly underlying the second magnetic layer. The second magnetic layer has a shape that is non-symmetrical, such that an average magnetization of a remnant state associated with the second magnetic layer has an in-plane component that is orthogonal to a current direction in the SOT generating layer.
