通过测量由Al/AlO/sub x/发射极、自旋阀基极和nSi集电极组成的热电子晶体管的集电极电流，研究了Fe/Au/Fe自旋阀中热电子的输运。在外加磁场作用下，集电极电流变化超过200%。这种变化的幅度随着发射极电压单调下降，并且在对应于Fe中少数自旋带的态密度的尖峰的电压（/spl sim/1.5V）处没有观察到异常。
Hot electron transport across an Fe/Au/Fe spin valve was examined by measuring a collector current of a hot electron transistor which was composed of an Al/AlO/sub x/ emitter, the spin-valve base and an nSi collector. The collector current changed more than 200% under application of magnetic field. The magnitude of this change decreased monotonously with emitter voltage, and no anomaly was observed at the voltage (/spl sim/1.5 V) corresponding to the sharp peak in the density of states of the minority spin bands in Fe.
