摘要：

We report strong evidence for coherent modes of moving Josephson vortices in mesas patterned on the surface of Bi2Sr2CaCu2Ox single crystals. The vortex How current-voltage curves are characterized by a sharp up-turn and the appearance of multiple branches as the current is ramped up and down at a fixed magnetic field and temperature. These results are consistent with weakly damped motion of Josephson vortices in which different coherent modes can occur in a close stack of Josephson coupled multilayers.
