Abstract
Giant magnetoresistance was observed in a disordered two-dimensional e lectron system in a variable-range hopping regime. The possibility of utilizing the phenomenon as a magnetic field sensor was demonstrated b y the detection of trapped vortices in a superconducting Pb film. The minimum size of such a device is discussed.
