Abstract

We have measured the magnetoresistance of a Bi antidot array film. The magnetoresistance exhibits a pronounced angular dependence on the direction of the magnetic field, e.g., the longitudinal relative magnetoresistance at 5 K displays an angular variation between 1.8 and 3.4 in a field of 4.9 T. The effect is the result of the interference between cigar-shaped regions of strong current distortions around the voids in the Bi film. The measurements can be understood and quantitatively reproduced by theoretical calculations.
