英文摘要
We have found that spin relaxation is suppressed in narrow InGaAs wires. Furthermore, the spin relaxation length is much enhanced by controlling spin-orbit interaction through gate voltage on top of the InGaAs wires. We have confirmed that magnetic anisotropy of magnetic semiconductor GaMnAs can be artificially introduced by making its wire-width narrower. A fabricated GaMnAs double-tunnel-barrier transistor has shown a current gain (=corrector current/base current) under particular bias condition.
