Figure 1 (IMAGE) Tohoku University Caption A film stack of the developed MTJ with the multilayered ferromagnetic structure. Shape anisotropy is enhanced by increasing the thickness of CoFeB and decreasing the number of CoFeB/MgO layers. Interfacial anisotropy is enhanced by increasing the number of CoFeB/MgO layers.
