K. Onabe et al., Superconducting property of Y1Ba2Cu3Ox films formed on silver substrates by continuous chemical vapor deposition technique, IEEE APPL S, 11(1), 2001, pp. 3150-3153
A new CVD system that equipped a triple-reactor was developed to improve th
e forming rate or the superconducting tape, Three-layered Y123 films with g
ood crystallinity covering the total thickness were obtained directly on ro
ll milled non-textured Ag tapes by using this triple-stage CVD system. 11 m
long Y123 tape with uniform Jc of 3.0x10(4) A/cm(2) at 77 K, 0 T was succe
ssfully prepared on roll milled non-textured Ag tape at a forming rate of 3
.0 m/h, Y123 films formed directly on the cube-textured Ag{100}< 001 > tape
s showed two types of orientation, cube-on-cube and diagonal-on-cube, betwe
en Y123 and Ag, On the other hand, Sm123 and Nd123 films showed the simple
orientation, cube-on-cube, so these films were expected to improve the in-p
lane alignment of Y123 him by inserting them as the intermediate layer.
