Abstract

Recently, spin interference effect based on the Rashba effect in a square loop (SL) geometry is proposed theoretically [Koga et al, Phys. Rev. B 70, 161302(R) (2004)] and demonstrated experimentally [Koga et al., Phys. Rev. B 74 in press] using In0.52Al0.48As/In0.53Ga 0.47As/In0.52Al0.48As quantum wells (QW), where the spin precession angle θ per side of the SL can be controlled by the applied gate voltage via the Rashba spin-orbit coupling constant α. In the present work, we include the effect of the bulk inversion asymmetry, so-called Dresselhaus term, in our model calculation. We found that the agreement between the experimental and simulation results are greatly improved by the inclusion of the Dresselhaus term in the model calculation.
