Superconductors having controlled laminar pinning centers, and method of manufacturing same

摘要: A multifilament superconductor having continuous, non-random pinning centers and including a plurality of parallel superconductive subfilaments uniform cross-sectional area, the being embedded in generally hexagonal jackets, jackets together forming structure honeycomb-like cross-section, wall thickness that is substantially an integral multiple coherence length predetermined field, continuous paths for fluxoids across superconductor, whereby total density said increased, critical field strength enhanced.
