Photographs of two fully grown YBCO crystals (on millimetre square graph papers) processed by ISSA seeding: top views (a) and (c) before and (b) and (d) after splitting off their seeding constructions. Distances between mini-buffers (D) are 7 and 10 mm for samples in (a) and (c), respectively. (e) Schematic illustration of the route of ISSA seeded YBCO growth. |
