Abstract
The high transport critical current density (J(c) > 500 kA/cm(2) at 4.2 K,
10 T is obtained in the Bi-2212/Ag multilayer tapes fabricated by using PAI
R (Pre-Annealing and Intermediate Rolling) and melt-solidification process.
This J(c) value is twice higher than existing high-quality Bi-2212/Ag tape
s (250 kA/cm(2)), By applying PAIR process to Bi-2212/Ag tapes, Bi-2212 gra
in alignment is much improved and a large J(c) enhancement is achieved. J(c
) has been increased strongly by performing pre-annealing at 840 degrees C
in oxygen (1 atm) and intermediate rolling with 25% deformation.
