Abstract
We study the magnetic field dependence of the correlation field Δ B c and amplitude δ gof the conductance fluctuations, observed in the low temperature magnetoresistance of GaAs/AlGaAs split-gate wires. Near zero field, universality of quantum interference is retained and the magnetoresistance shows universal conductance fluctuations. At high magnetic fields, although the discrete Landau level quantization becomes resolved. Δ B c and δ gare found to increase linearly with magnetic field, with a slope which depends upon the nature of electron scatterings in the wire.
