We have observed a tendency toward locking of the Aharonov-Bohm effect phase shift, in doubly connected, quasi-one-dimensional GaAsAlxGa1-xAs devices. The resistances of adjacent segments within a device exhibit periodic modulations, due to magnetic flux penetrating the area enclosed by the doubly connected geometry, which are phase-shifted from each other by a value of close to 180°. This phase shift value persists over a range of 200 periods (∼4kGauss in magnetic field), and is observed for various current-voltage configurations. © 1988.
