摘要: | Static and dynamic distribution of the superconducting condensate order parameters and current density is studied by numerical simulation of the 2D time-dependent Ginzburg-Landau equations The vortex flux lattice in layered type-II superconductors under magnetic field above the lower critical field is described by the order parameters Moreover the pinning effect has been considered in this work The Abrikosov lattice which is hexagonal in the static case is deformed due to the size of pinning centers The dynamical order parameters distribution shows that the vortex transport (flux flow) is conducted via diffusive motion of the so-called interstitial vortices The trajectories for interstitial vortices with different sizes of pinning centers are shown (C) 2010 Elsevier BV All rights reserved |
