Typical MR curves of (Cr2O3/Fe2O3) NOL spin valve at 150 K of the cycle number n = 1 (black filled circles) and n = 10 (red open squares). Applied sense current is 0.1 mA in the pinned direction.
MR(n)/MR(n = 2) as a function of the cycle number n for the (Cr2O3/Fe2O3) NOL for sense currents in the pinned (a) and inverse pinned (b) directions at 150 K. Blue open circles, red open squares, and black filled squares represent currents of 10 mA, 0.1 mA, and 0.001 mA, respectively.
κMR as a function of sense current in the pinned (red filled squares) and inverse pinned (blue open squares) directions at 150 K.
Temperature dependence of Δκ MR for currents in the pinned (red filled squares) and inverse pinned (blue open squares) directions.
Cross-sectional TEM image of Cr2O3 NOL (above) and simulated model of NOL (below). White and black cells represent Co0.9Fe0.1 metal and Cr2O3/Fe2O3 oxide, respectively.
