摘要：

The magnetic-field dependence of the conductance of two opposite point contacts in series is studied experimentally, for magnetic fields extending into the quantum Hall effect regime. The magnetoconductance has a nonmonotonic, camel-back shape, in quantitative agreement with a recent theory. In addition, Aharonov"Bohm-type periodic magnetoconductance oscillations are observed, which are attributed to circulating edge states in a shallow potential basin between the point contacts. © 1990 The American Physical Society.
