Vortex lattice in LiFeAs superconductor in the two-band Ginzburg-Landau model

Abstract

Time dependent equations of the two band Ginzburg-Landau model are simulated numerically. Calculations are performed for square thin films of the LiFeAs two band superconductor in the vicinity of the superconducting transition temperature in the transverse magnetic field; the quasi hexagonal nature of the vortex lattice in the intermediate state is demonstrated.
