Abstract
A spin-transfer torque magnetic tunnel junction includes a layer stack with a pinned magnetic layer and a free magnetic layer, and an insulating barrier layer there-between. Each of the magnetic layers has an out-of-plane magnetization orientation. The junction is configured so as to allow a spin-polarized current flow generated from one of the two magnetic layers to the other to initiate an asymmetrical switching of the magnetization orientation of the free layer. The switching is off-centered toward an edge of the stack. The junction may allow a spin-polarized current flow that is off-centered toward an edge of the stack, from one of the two magnetic layers to the other, to initiate the asymmetrical switching. Related devices and methods of operation are also provided.
