Double transition and vortex-sheet structure in multi-component superconductors

摘要

A simulation study using the time-dependent Ginzburg Landau theory is performed for the vortex state in two-component superconductors, in order to investigate the nature of the double transition and exotic vortex state, such as the vortex structure at the domain wall. Half flux-quantum vortices are aligned along the domain wall, forming vortex-sheet structure. The flux flow and the pinning of the vortex sheet are also investigated. (c) 2005 Elsevier B.V.
