Rubans supraconducteurs en bismuth(2223) de grande longueur.

Long lengths of bismuth(2223) superconducting tapes.

Résumé

The optimization of the fabrication of mono- and multifilamentary bismuth(2223) tapes has been carried out in order to improve their transport properties on long lengths. At present, critical current densities as high as 34.5 and 28 kilo-amperes/cm2 have been reproducibly achieved at the liquid-nitrogen temperature on long mono- and multifilamentary tapes, respectively. The behaviour in magnetic field of the transport properties of these tapes has been studied. At 77 K, a field of 1 T applied along the ab-planes of the bismuth(2223) grains reduces the critical current by a factor of five and three in mono- and multifilamentary samples, respectively.
