Claim 0:
1. A method of making a perpendicular magnetic tunnel junction (pMTJ) element, comprising:
forming a magnetic pinning structure, wherein forming the magnetic pinning structure comprises:
forming a perpendicular synthetic antiferromagnetic (pSAF) stack,
forming an oxide buffer (OB) layer on top of the pSAF stack, and
forming a cube-textured reference layer, wherein forming the cube-textured reference layer comprises depositing a texture starting (TS) layer on top of the oxide buffer layer;

depositing a tunnel barrier layer on top of the magnetic pinning structure;
depositing a magnetic free layer on top of the tunnel barrier layer and having a magnetic anisotropy perpendicular to a film surface and having a variable magnetization direction; and, further comprising: performing a tensile strain quenching (TSQ) process immediately after at least one of depositing the TS layer and depositing the tunnel barrier layer,, wherein performing said TSQ process induces a BCC or L10 superlattice structure and a (100) crystal texture in the TS layer.
