    Transport properties of submicron rings fabricated on the basis of two-dimensional electron gas in a GaAs double quantum well are studied. It is shown that, in such interferometers, the Aharonov-Bohm effect is caused by coherent processes in two weakly coupled rings. In these interferometers, a...
