Flux distribution in superconducting films with holes
Copyright policy )Flux distribution in superconducting films with holes
Flux penetration into type-II superconducing films is simulated for transverse applied magnetic field and flux creep dynamics. The films contain macroscopic, non-conducting holes and we suggest a new method to introduce the holes in the simulation formalism. The method implies reconstruction of the magnetic field change inside the hole. We find that in the region between the hole and the edge the current density is compressed so that the flux density is slightly reduced, but the traffic of flux is significantly increased. The results are in good agreement with magneto-optical studies of flux distributions in YBCO films.
