Abstract
We have measured the magnetoresistance measurements of a 2D electron g as subjected to a periodic magnetic field created by the presence of t ype II superconducting stripes on the surface of the heterostructure. We observe oscillatory behaviour due to a commensurability effect betw een the cyclotron radius and the period of the magnetic field. The res ults can be understood in terms of a simple semi-classical theory.
