Abstract :
Magnetotransport in GaAs/AlGaAs quantum wells with ultrashort period (View the MathML source) unidirectional potential modulation has been studied. Systematic suppression of the exchange enhancement mechanism for quantum Hall spin gap is observed. A reproducible a periodic fluctuation of magnetoresistance reminiscent of mesoscopic fluctuation is found in a certain sample.
