Abstract

The measurement of Fourier spectra of the Aharonov-Bohm oscillations in GaAs two-dimensional holes with a strong spin-orbit interaction was presented. The measurement revealed side peaks in addition to the center peak whose frequency corresponds to the radius of the mesoscopic ring. A comparison of the experimental data with results of simulations demonstrated that the origin of the side peaks was the Berry's phase.
