Abstract: Magnetic tunnel junctions (MTJ) suitable for spin transfer torque memory (STTM) devices, include perpendicular magnetic layers and one or more anisotropy enhancing layer(s) separated from a free magnetic layer by a crystallization barrier layer. In embodiments, an anisotropy enhancing layer improves perpendicular orientation of the free magnetic layer while the crystallization barrier improves tunnel magnetoresistance (TMR) ratio with better alignment of crystalline texture of the free magnetic layer with that of a tunneling layer.
