摘要：

Sweeping the magnetic field at low temperatures can result in metastable states of the system of two-dimensional electrons in GaAs/AlxGa1-xAs. These nonequilibrium states are stable in the range of filling factors 1/3<ν<1, but can be changed by an extremely small variation of magnetic field around ν1, which is accompanied by a drastic change in magnetoresistivity. We used this phenomenon to vary the disorder and to study its influence on the electronic properties of two-dimensional electrons in the regime of the fractional quantum Hall effect and, especially, in the vicinity of ν=1/2. © 1995 The American Physical Society.
