We report magnetoresistance measurements on a two-dimensional electron gas made from a high-mobility GaAs/Al[sub [ital x]]Ga[sub 1[minus][ital x]]As heterostructure, where the externally applied magnetic field was expelled from regions of the semiconductor by means of superconducting lead grains randomly distributed on the surface of the sample. A theoretical explanation in excellent agreement with the experiment is given within the framework of the semiclassical Boltzmann equation.
