Abstract
Many processes were utilized in order to produce YBa 2Cu 3O 7−δ (YBCO) bar samples, but up to now, the alignment of single domains with the bar axis was not optimized for power applications. A new process was elaborated to synthesise samples with optimized alignment: the Microwave Top Seeding Floating Zone (MTSFZ). The CeO 2 and SnO 2 doping YBCO composition was selected for its high superconducting properties. Samples of good quality were produced by MTSFZ in very short time thanks to a seed that initiated successfully the correct alignment. The superconducting properties evaluated by SQUID measurements were similar to the ones obtained with other texturing process: critical temperature near to 91 K and critical current density at 77 K in self field of 42 kA cm −2.
