- Abstract
Sweeping the magnetic field at low temperatures can result in metastable states of the system of two-dimensional electrons in GaAs/AlGaAs. These non-equilibrium 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 ν=1. We used this phenomenon to vary the disorder and to study its influence on the electronic properties of two-dimensional electrons in the vicinity of ν=1/2. The temperature dependence of σxx at ν=1/2 was analyzed, and logarithmic corrections to conductivity were found.
