Evolution of h/2e Aharonov–Bohm oscillation with the Zeeman energy around an antidot

We have investigated resonant tunneling experiments through a quantum antidot in the quantum Hall regime. When the two edge states with different spins of the lowest Landau level are localized around an antidot conductance exhibits the paired h/2e Aharonov–Bohm oscillations. Using a tilted magnetic field technique we observed evolution of the oscillation with the Zeeman energy. A concomitant change is observed in the conduction spectra at finite source–drain bias. These results are interpreted by the energy spacings between the single particle states with the same spin and the Zeeman splitting.
