The coherent coupling between electron Bloch and in‐plane cyclotron oscillations in semiconductor superlatttices in tilted electric and magnetic fields induces a unidirectional quasi‐DC current in analogy to the DC Fiske effect observed when a superconductor Josephson junction or a superfluid weak link is coupled to an electromagnetic respectively an acoustic resonator. In all cases, the coupling opens an elastic rectifying transport channel. We explore the effect for the case of a superlattice both experimentally and theoretically, and specifically address the influence of the coupling on the frequency of the magneto‐Bloch oscillations.
