Abstract

High quality, sharp cube textured Ni substrates have been fabricated by a cold rolling and a recrystallization annealing process. X ray results show that there are some problems to be noted in the prevalent quality evaluation for a cube textured Ni substrate. In-plane-aligned, c axis-oriented YBa/sub 2/Cu/sub 3/O/sub 7/ (YBCO) thick films were grown on the textured Ni substrate with self-oxidized NiO intermediate layer by an ink-printed and floating zone heating method. The values of the resistively measured T/sub c/ (onset) were 86 K. This is a very useful and promising method for producing the long YBCO tapes with high J/sub c/, although J/sub c/ is lower at present.
