Two-dimensional electron gases in GaAs/Al_xGa_1−xAs heterostructures are exposed to combinations of periodic electric and magnetic fields. These so-called superlattices are realized with customary lithography methods and are composed of a two-dimensional antidot array and a two-dimensional magnetic lattice. The resulting nontrivial electronic trajectories are expected to manifest themselves in novel magnetoresistivity resonances at cryogenic temperatures. To interpret the experimentally obtained results numerical simulations of the electron dynamics within the semiclassical Kubo formalism are used.
