Abstract

Due to the low yttrium solubility in Ba-Cu-0 liquid, the growth rate of a YBa2Cu3O7 (Y123) grain in the liquid is low. It takes a few hundred hours to fabricate a large single grain YBCO superconductor. A multi-seeding technique may shorten the processing time needed for the fabrication of large area textured YBCO superconductors. In this study, we tried a top-seeded melt growth process combined with multi-seeding. The processing variables, the growth mode of Y123 grains at the top surfaces, and the levitation forces and trapped magnetic fields of the multi-seeded sample are reported.
