摘要：
We propose a spin interferometer using Rashba spin - orbit interaction. A spin interference effect is demonstrated in small arrays of mesoscopic InGaAs rings. This spin interference is the time reversal Aharonov-Casher ( AC) effect. The AC interference oscillations are controlled over several periods. This result shows evidence for electrical manipulation of the spin precession angle in an InGaAs two- dimensional electron gas channel. We control the precession rate in a precise and predictable way with an electrostatic gate.
