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