Oscillations have been observed in the magnetoresistance of a 2D electron gas in an artificial 2D periodic lattice of scatterers. The period of these oscillations along the magnetic field scale is *he/ *(*2eS)*, where *S *is the area of the square associated with the lattice period. This oscillation period is determined by the Aharonov-Bohm effect of electrons which interfere as they are scattered by the lattice.
