Cuprate high-temperature superconductors have matured to the extent that many applications are now possible and indeed are currently being rolled out. In our Institute these include MRI , NMR, flux pumps, rotating machinery, transformers, and next-generation aerospace propulsion. Key to these applications is wire performance as governed by critical current density, Jc. By studying over 100 data sets for every class, type and symmetry of superconductor we show that Jc in self-field is actually a thermodynamic parameter, independent of the pinning commonly believed to underlie its behaviour and governed only by the superfluid density. We report a new critical state in the Meissner state and confirm this through measurements of current and field distribution across practical conductors.
