Abstract

A superconductive conductor protected against partial transitions, the conductor comprising a superconductive region made up of superconductive filaments embedded in a non-superconductive metal matrix, and a non-superconductive metal region, wherein the cold resistivity of the non-superconductive metal region is less than half the overall cold resistivity of the superconductive region in the non-superconductive state, the superconductive region and the non-superconductive metal region being merely in mechanical contact, without cohesion.
