摘要：

A strong correlation between the low-field magnetoresistance anomaly and the temperature dependence of the quantum correction to the conductance in a disordered 2D system was experimentally observed in the mT range. The behavior contradicting the generally accepted logarithmic scaling was accounted for by a phase-breaking process due to the Aharonov-Bohm effect. Copyright (C) 1996 Elsevier Science Ltd
