Abstract
Flux penetration into type-II superconducting films is simulated for transverse applied magnetic field and flux creep dynamics. The films contain macroscopic nonconducting holes, and we introduce the holes in the simulation formalism by reconstruction of the magnetic field change inside the holes. We find that the holes induce a region of reduced flux density extending toward the nearest sample edge, in addition to the parabolic d lines. The region of reduced flux density is due to compression of current streamlines and is accompanied by a significantly enhanced flux traffic. The results are compared to and found to be in good agreement with experimental magneto-optical images of YBa2Cu3Ox films including holes and slits.
