摘要：
We observed a multi-branch behavior in the Aux-flow branch of current-voltage characteristics of stacks fabricated along the c axis in La2-xSrxCuO4 single crystals. The voltage increases with increasing an external magnetic field applied parallel to the ab plane, The multi-branch behavior may originate from a chaotic motion of Josephson vortices with many velocity modes, (C) 2000 Elsevier Science B.V.
