摘要：

Magnetoresistance of a two-dimensional electron gas in a quasiperiodic lattice (Penrose tiling) of antidots has been studied. Magnetoresistance oscillations in a magnetic field were found when the cyclotron diameter 2R(L) was equal to the minimal distance between the centers of the antidots d(min), and for 2R(L) = 1. 62d(min). In contrast to the periodic lattice, where these oscillations originate from trajectories skipping along the array, in a quasiperiodic system commensurability oscillations of the magnetoresistance were suggested to be due to oscillations of the electrons scattered by the antidots.
