Abstract
A theory is developed for the recently discovered magnetoresistance oscillations in a two-dimensional electron gas subject to a weak periodic potential. The effect is explained as a resonance between the periodic cyclotron orbit motion and the oscillating E×B drift of the orbit center induced by a potential grating.Keywords
