A magnetic tunnel junction with perpendicular magnetic anisotropy (PMA MTJ) is disclosed wherein a free layer has an interface with a tunnel barrier and a second interface with an oxide layer. A lattice-matching layer adjoins an opposite side of the oxide layer with respect to the free layer and is comprised of Co.sub.XFe.sub.YNi.sub.ZL.sub.WM.sub.V or Co.sub.XFe.sub.YNi.sub.ZL.sub.W wherein L is one of B, Zr, Nb, Hf, Mo, Cu, Cr, Mg, Ta, Ti, Au, Ag, or P, and M is one of Mo, Mg, Ta, Cr, W, or V, (x+y+z+w+v)=100 atomic %, x+y>0, and each of v and w are >0. The lattice-matching layer grows a BCC structure during annealing at about 400? C. thereby promoting BCC structure growth in the oxide layer. As a result, free layer PMA is enhanced and maintained to yield improved thermal stability.
