Abstract
A novel type of magnetoresistance oscillations is predicted when a two-dimensional electron gas is subjected to a magnetic field that varies periodically in both lateral directions. A semiclassical model is examined in perturbation theory and numerically. The field inhomogeneities cause deterministic diffusion which leads to an oscillating enhancement of the conductivity when elastic scattering is included.Keywords
