| Abstract(in English) | In-phase coherent motion of Josephson vortices over an intrinsic Josephson junction (IJJ) stacks is required for flux-flow oscillation and plasma oscillation using Bi-2212 IJJ stacks. We have been observed Shapiro-step-like responses for the Bi-2212 IJJ stacks in the flux-flow state with cooperation of periodic potentials introduced in the IJJ along the direction of vortex motion. This result indicates that the periodic potentials are effective to develop the in-phase coherent motion of the Josephson vortices over the IJJ. To analyze this phenomenon in detail, we simulated Josephson vortex dynamics with periodic pining potentials, and reproduced Shapiro-step-like responses. |
