Preparation of Partial-Melted Sm-Ba-Cu-O Bulk Superconductor

Article Preview

We prepared SmBa2Cu3Oy (SmBCO) superconducting bulks by partial melting growth with a top seed. From the results, we found that the SmBCO bulks prepared by melting process showed good superconductivity, where the critical temperature Tc and the temperature transition width ΔT of the bulk were 94K and about 1K, respectively. The as-prepared bulks required annealing at 500°C for 24h to improve the superconductivity. However, the characteristics of the bulks may be improved by more detailed study, for example optimum preparation and annealing conditions.
