Abstract
Abstract The nonlocal Shubnikov-de Haas (SdH) oscillations in GaAs/AlGaAs mesoscopic multi-terminal wires have been measured. The ampitude of the oscillations decreases in general with increasing nonlocal separation length (ΔL) between the nominal current path and the voltage probes. The amplitude also becomes weak, when there exist branches with electrodes between the current and the voltage probes which have ostensibly nothing to do with the voltage measurement. The behavior is interpreted by the combination of the edge and bulk current at high magnetic fields.
