    Abstract:
    We have observed the Aharonov-Bohm effect in the magnetoresistance of doubly connected geometries fabricated in high-mobility GaAs/AlGaAs heterostructures. Periodic oscillations in the resistance associated with the fluxs penetrating the annulus are suppressed above c5, where c is the cyclotron frequency and is the scattering time, while fluctuations in the resistance as a function of magnetic field are observed for 0
