This invention relates to a superconducting wire used for a superconducting magnet, etc. and to a method of manufacturing the wire. A conventional superconducting wire has a low critical current density (Jc) and is unsuitable for a superconducting magnet, etc. According to this invention, a pinning center made of a non-superconducting substance is introduced into a superconducting substance, so that the Jc of the superconducting wire is remarkably improved by the pin stop effect of the pinning center. In addition, such problems in the prior art, that the manufacture is time-consuming and the manufacturing cost is high, have been overcome. Since the superconducting wire of this invention has a remarkably improved Jc, it is appropriate as a wire for a superconducting magnet.

L'invention porte sur un fil supraconducteur pour un aimant supraconducteur et sur la méthode de fabrication de ce fil. Les fils supraconducteurs actuels ont une faible densité de courant critique (Jc) et sont inappropriés aux aimants supraconducteurs, etc. Dans la présente invention, un centre de fixation fait d'une substance supraconductrice est introduit dans une substance supraconductrice et la fixation produite amène une élévation remarquable de Jc dans le fil supraconducteur. Par ailleurs, les problèmes de la technologie actuelle constitués par le prix de revient élevé de la fabrication et le fait que celle-ci prend beaucoup de temps ont été résolus. Ayant une densité de courant critique Jc considérablement accrue, le fil supraconducteur de cette invention est approprié aux aimants supraconducteurs.
