Abstract


  • Based on a model appropriate for “marginally type-II” superconducting system, we study the dynamics of

    vortices with competing interactions by Langevin dynamics simulation. In addition to pinned states and plastic

    flow, we find that the moving vortex system forms ordered bubble configurations and stripe structures, depending

    on pinning strength and driving force. The vortex system exhibits a marked hysteresis in its velocity-force

    characteristic, which results from a dynamical stripe reordering due to intervortex attraction.
