Abstract
YBCO/Ag tapes prepared using nanosized YBCO powder are currently the best powder-in-tube YBCO tapes with their I-c = 5.02 A and J(c) = 3300 A/cm(2) in self-field and at 77 K. The texture of these tapes was studied by removing the silver with mercury and then measuring the texture of the surface with X-ray diffraction. A clear correlation between 1, and c-axis texture is found and even some evidence of ab-texturing in the very best tapes. Less texture is found when the middle of the filament is exposed by cutting the tape. This suggests that multifilament tapes with smaller filament cross-section should have even higher I-c.
