摘要：

We have studied commensurability oscillations in magnetoresistance (MR) of antidot arrays by changing the antidot shape. For the bar-shaped antidot array, we found the clear dependence of the amplitude of commensurability oscillations on the current direction. This feature was successfully reproduced by numerical calculations. Based on these results, we discuss the origin of the commensurability oscillations. We have also studied antidot arrays with other antidot shapes experimentally and numerically. (C) 1998 Elsevier Science B.V. All rights reserved.
