摘要：
By two-dimensional ballistic magnetotransport calculations, it is demonstrated that large-scale resistance peaks, typical of small ring interferometers in zero magnetic field, are suppressed at B∼1 T. This result is explained by the peculiarities of the interference pattern at the confluence sites of quantum wires and is in qualitative agreement with experimental data.
