Abstract
We report on -periodic oscillations in the magnetoresistance of a circular magnetic billiard. These arise from singly periodic orbits that return to their point of departure after bounces on the billiard. A semiclassical calculation of the magnetic field increment required to depin annulus and is in good agreement with the measured period of the resistance oscillations.
