The keynote speaker and half of the invited speakers elaborated on the critical current density in the oxide superconductors. Major subjects covered were weak link phenomena, flux creep and novel processing approaches, melt texturing and fabrication of wires/tapes/filaments. In concurrent sessions progress on the thin film fabrication was presented. Major trends included the epitaxial deposition of films to enhance critical current density and the deposition of films at low temperaturews.
