(Color online) Magnetization curves of the MgO barrier (1 nm)/FeB (2 nm)/MgO cap plane films. Magnetic fields were applied in the perpendicular-to-plane (a) and in-plane (b) directions.
(Color online) Magnetization and saturation field of the MgO barrier (1 nm)/FeB (2 nm)/MgO cap plane films.
(Color online) MR ratio and resistance-area product of the MTJ films measured using the current-in-plane-tunneling method.
(Color online) MR curves of microfabricated MTJs with different layer thicknesses of MgO cap. In the figure, magnetization configurations of the FeB free and CoFeB reference layers are also schematically interposed.
