Abstract

In investigation of commensurability oscillations in antidot lattices, we find a relation between the resistivity ρ_xx and the differentiated Hall resistivity dρ_xy/dB, where B is the strength of the magnetic field. All peaks of ρ_xx exactly correspond to those of dρ_xy/dB. This coincidence is direct evidence that the extended Drude model for the oscillations cannot fully explain the magnetoresistance experimentally observed in antidot lattices.
