The nonlocal resistance of a 2D electron gas has been studied under conditions of the quantum Hall effect in the nonlinear regime. A breakdown of the quantum Hall effect has been observed in a nonlocal geometry. Nonlinear features have been observed in the behavior of the nonlocal resistance in the dissipative regime. The results found are interpreted on the basis of a model of edge current states for which the length scale for mixing with bulk states is determined by the magnitude and direction of the current through the sample. © 1994 American Institute of Physics.
