Abstract
The nonlinear response to an external-electric field is studied for classic al noninteracting charged particles under the influence of a uniform magnet ic field, a periodic potential, and an effective friction force. We find nu merical and analytical evidence that the ratio of transverse to longitudina l resistance forms a Devil's staircase. The staircase is attributed to the dynamical phenomenon of mode-locking.
