Multiseeding with (100)/(100) grain junctions in top-seeded melt growth processed YBCO superconductors

摘要

Multiseeding with (100)/(100) grain junctions of top-seeded melt growth (TSMG) processed YBCO superconductors was studied. Multiple seeding shortened the processing time for the fabrication of TSMG-processed YBCO superconductors. The relationship among the number of seeds, the levitation forces and the trapped magnetic fields of the TSMG-processed YBCO samples is reported. The characteristic of the (100)/(100) grain junction is discussed in terms of a wetting angle of a melt. (C) 2000 Elsevier Science B.V. All rights reserved. [References: 18]
