摘要：

We investigate the low-field magnetoresistance p,, perpendicular to a one-dimensional periodic potential which is imposed upon a two-dimensional electron gas in GaAs-AlxGa1-xAs heterojunctions. Distinct low field anomalies and a crossover from positive to large negative magnetoresistance with increasing potential strength unveil the important role of anisotropic relaxation processes in strongly modulated electron systems.
