本文报道了小型（<0.01 μ m 2） Ni/NiO/Co隧道结阵列的实验结果。在高温或高偏置条件下，由于电极磁化相对方向的变化，我们观察到磁电阻。在库仑阻断机制下，磁电阻与偏置相关，观察到高达40%的大负磁电阻。
We report experimental results on the arrays of small (<0.01 µ m 2 ) Ni/NiO/Co tunnel junctions. At high temperatures or high bias conditions, we observed magnetoresistance due to changes in the relative orientation of magnetization of the electrodes. In the Coulomb blockade regime, magnetoresistance is bias-dependent and a large negative magnetoresistance of up to 40% was observed.
