Dependence of fcc crystallinity of the MgO tunneling barrier on the bridging and capping materials for the p-MTJ spin-valve. (a) p-MTJ spin-valve with a Ta bridging and capping layer and (b) p-MTJ spin-valve with a W bridging and capping layer. Cross-sectional high-resolution TEM images observed at an acceleration voltage of 200 KeV.
