Abstract

We demonstrate a spin interference effect in a small array of InGaAs mesoscopic rings. The spin interference is based on 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 gas channel. We observe a reproducible half-oscillation, which may be attributed to the competition between the Rashba SOI and the Dresselhaus SOI.
