Theory of Flux Penetration Effects Below H c1 in Multifilamentary Superconductors

Markworth, A. J. / Collings, E. W. / McCoy, J. K. / Stroud, D.

Abstract Results are presented of magnetic-field calculations for multifilamentary (MF) superconductors, taking into account the penetration of magnetic flux into individual filaments. The filaments are assumed to be circular in cross section, infinitely long, and arranged parallel to one another on a hexagonal lattice. The externally applied magnetic field is taken to be directed perpendicular to the filament length. The problem is simplified by treating the medium as being effectively uniform in a plane perpendicular to the filament length, and a self-consistent formalism is used to calculate the interfilamentary magnetic field. Flux penetration into the filaments is described using the London theory. Magnetic fields outside and inside the filaments are calculated as functions of filament radius, the London penetration depth, the area fraction covered by filament cross sections, and the shape of the filament bundle.
