✦ Synopsis

Mono-domain YBa 2 Cu 3 O 7Àx (Y123) bulk superconductors have been processed using seeded infiltration growth technique (SIG). The combination of melt infiltrated liquid source (Ba 3 Cu 5 O 8 ) into the Y 2 BaCuO 5 (Y211) pre-form and the nucleation of Y123 domain from SmBa 2 Cu 3 O 7 crystal seed has been investigated. The different configurations of SIG process were compared in this study. In addition, the effect of the starting Y211 particles size has been studied. The results reveal that, the Y211 particle size and different configurations strongly influence the properties of the final bulk superconductor sample.
