抄録: Efficient gate control of spin-valve signals and Hanle signals was achieved in a GaAs channel with a p-i-n back-gate structure. Experiments showed that the amplitude of the spin-valve signal (Delta V-NL) under constant-injection-current conditions increased for a cross nonlocal geometry when the channel was depleted by the gate voltage (V-G). In contrast, the V-G dependence of Delta V-NL for a nonlocal geometry was complicated. The gate modulation efficiency of spin signals was approximately 50 times that with a graphene or Si channel.
