Multi-seeded melt crystallization of YBCO bulk material for cryogenic applications
- 1. Institute of Solid State and Materials Research Dresden, PO Box 270016, 01171 Dresden (Germany)
Description
YBCO bulk materials were crystallized by a multi-seeded melt growth process. Up to four biaxial oriented Sm-123 seeds were placed on the top of rectangular shaped YBCO bars (up to 100 x 40 x 15 mm3). The oriented grown single grains are joined by partially coherent grain boundaries with an improved current transport capability and high levitation forces with overall values of 55-65 N. Segregation of nonsuperconducting rest melt and microcracks limit the current transport across the grain boundary. (author)
