摘要：

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/AlOx 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 (similar to 1.5 V) corresponding to the sharp peak in the density of states of the minority spin bands in Fe.
