Abstract

A simulation study using the time-dependent Ginzburg-Landau theory is performed for the vortex state in two-component superconductors, such as ${\mathrm{PrOs}}_{4}{\mathrm{Sb}}_{12}$. We investigate the flux flow and the pinning of the vortex sheet structure. We find a domain wall that traps half flux-quantum vortices and moves with the flux flow. In the pinning case, we observe an emitting process of a conventional vortex from the vortex sheet by combining a pair of half flux-quantum vortices.
