Abstract

Abstract TFA-MOD (Metal Organic Deposition using Trifluoro-acetates) process is of considerable practical concern for future applications since it can fabricate high performance coated conductors (CCs) with low cost. In this study, we developed the process for fabricating thick films in BZO nanoparticle doped Y 0.77 Gd 0.23 Ba 1.5 Cu 3 O y (YGdBCO) CCs in order to realize high I c values under magnetic field. The effect of RTR (Reel To Reel)-dip-coating conditions on microstructure, J c(- B -θ) properties, etc. was investigated in order to fabricate crack-free thick and high performance films. A BZO doped YGdBCO film with uniform 3.0 μm thickness showed the high in-field I c and J c values of 55.6 A/cm-w and 0.18 MA/cm 2 @77.8K, 3T, respectively.
