ELECTRIC, MAGNETIC AND TRANSPORT CRITICAL CURRENT DENSITY BEHAVIOUR OF THE 2201, 2212 AND 2223 PHASES OF BSCCO.

Summary

THE AUTHORS HAVE STUDIED THE ELECTRICAL PROPERTIES OF POLYCRYSTALLINE PELLETS OF THE HIGH-CRITICAL TEMPERATURE SUPERCONDUCTING PHASES OCCURRING IN THE BSCCO SYSTEM. PELLETS CONTAINING THE 2223 PHASE HAVING ZERO RESISTANCE BELOW 105 K WERE OBTAINED. FOR THE 2212 AND 2223 PHASES, THE TRANSPORT CRITICAL CURRENT DENSITY WAS MEASURED AS A FUNCTION OF TEMPERATURE AND OF THE EXTERNALLY APPLIED MAGNETIC FIELD. AS PREVIOUSLY FOUND FOR YBCO, RESULTS ARE CONSISTENT WITH THE OCCURRENCE OF A WEAK SUPERCONDUCTING COUPLING AMONG THE GRAINS. SUCH COUPLING WAS, HOWEVER, NOTICEABLY STRONGER FOR THE 2223 PHASE THAN FOR THE 2212 PHASE.
