Abstract

The magnetic field dependence of aperiodic fluctuations has been studied by means of analysing the Fourier transform of the magnetoresistance in narrow GaAs/AlGaAs wires. Near the critical field of ωcτ=1, the decay of aperiodic fluctuations, which is observed on the low frequency side of the Fourier spectra, shifts to low frequencies. The shift can be explained by reduction of the effective area for the interference.
