Abstract
We have studied the magnetoresistance of magnetic surface superlattices in which arrays of square cobalt dots are deposited on top of a GaAs/AlGaAs heterostructure. For a magnetic field inclined to the normal to the sample, strong commensurability oscillations are seen when the in-plane component of the field is parallel to the direction of current flow, but there is no such structure when the in-plane field is rotated through 90 degrees . For a normal field, the commensurability oscillations are weak and out of phase for transport in the different cleavage directions. All these results are in agreement with a recent semi-classical model of transport in 2-dimensional lateral superlattices.
