Vortex dynamics for low-? type-II superconductors

Xu, X., Fangohr, H., Wang, Z., Gu, M., Liu, S., Shi, D. and Dou, S. (2011) Vortex dynamics for low-? type-II superconductors Physical Review B, 84, (1) (doi:10.1103/PhysRevB.84.014515).

Record type: Article


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.
