摘要: At voltages larger than 1.2 V Co/Al2O3/Co(–Fe) magnetic tunnel junctions show almost immediate breakdown, leading to a decrease in (magneto) resistance. The position of the shorts formed is visualized by making use liquid crystal film on top junction. breakdown series nominally identical measured voltage-ramp experiment increased with ramp rate. extrapolated lifetime, at lower voltages, evaluated.
