In magnetotransport measurements on arrays of cross-shaped antidots, we observe pronounced features in both the longitudinal and transverse magnetoresistivities $\rho$$_{xx}$ and $\rho$$_{xy}$, which cannot be understood within the simple framework of commensurability between cyclotron radius and superlattice period. These resonances can be regarded as magnetotransport fingerprints of the ...
