Transport properties of YBa2Cu3O7 and NdBa2Cu3O7 films prepared on textured Ag tapes

We obtained the {100}<001> textured Ag tape with both a good biaxial crystal orientation and a smooth surface, by precise control of the rolling process parameters. On this {100}<001> textured Ag tape, YBa₂Cu₃O₇ (Y-123) and NdBa₂Cu₃O₇ (Nd-123) films were deposited by using a pulsed laser deposition method. "Y-123/Nd-123/{100}<001> textured Ag tape" sample had both good biaxial orientation and smooth surface, as a result, relatively high J_c of 0.57×10⁶ A/cm² at 77 K in self field was achieved. Present J_c value is not competitive comparing with the other techniques for coated conductors (CC), such as IBAD or RABiTS, however, it is very promising. We believe that the J_c of CC using {100}<001> textured Ag tapes will increase after optimizing the Y-123 deposition process.
