Abstract

To explore commensurate oscillations in antidot lattice, the dependence on the antidot array number (N) perpendicular to the current flow direction is studied. With decreasing JV, the peaks of the oscillations become small. Even at N = 1, the peaks do not vanish. The relationship between the oscillations and the current flow direction is investigated in rectangular antidot lattices which are rotated at five different angles with respect to the current flow direction. At = 0°, the shorter side of the cell is perpendicular to the current flow direction. The main peak magnetic field of the oscillations is determined by the period of the shorter side of the cell. The peak height decreases with increasing I and vanishes at = 90°.
