Abstract
A magnetoresistive random-access memory (MRAM) device is disclosed. The device described herein has a spin current injection capping layer between the free layer of a magnetic tunnel junction and the orthogonal polarizer layer. The spin current injection capping layer maximizes the spin torque through very efficient spin current injection from the polarizer. The spin current injection capping layer can be comprised of a layer of MgO and a layer of a ferromagnetic material.
