Magnetic vortex relaxation in external magnetic field

Slow relaxation of magnetic vortices in type-II superconductor in a presence of the external magnetic field of 5% of upper critical field (applied in vertical direction). The final state of vortex lines approaches to Abrikosov lattice.

Shown is the iso-surface of squared order parameter |ψ|² from three-dimensional time-dependent Ginzburg-Landau (TDGL) simulations.

TDGL solver is described in "Stable large-scale solver for Ginzburg-Landau equations for superconductors" by Ivan A. Sadovskyy, Alexei E. Koshelev, Carolyn L. Phillips, Dmitry A. Karpeyev, Andreas Glatz
