Abstract

In this study, single-core and multi-core Tl1212 tapes were fabricated from Tl-1212 superconducting powder of Tl0.5Pb0.5Sr 1.8Yb0.2CaCu2O7 starting composition derived by conventional solid state synthesis. Single core tapes showed maximum Jc and enhanced 1212 phase formation were achieved for tapes annealed at a higher temperature for a longer duration. Multi core tapes showed a general increase in Ic and Jc with the number of tapes core. The highest Jc of 521 A/cm2 was observed for the 4-core tapes annealed at 870 °C for 90 minutes. The initial drastic drop of the tapes Jc in low magnetic fields (≤1T) indicates limitation on tapes performance by weak links. The low Jc of the tapes may be due to the lack of texture in the tapes core as revealed by SEM.
