Ni by an electroplating technique and Sr_0.95Nd_0.05TiO₃ by a PLD method were epitaxially grown on a biaxially textured pure Cu tape as conductive buffer layers, and then a YBCO was epitaxially grown on the Sr_0.95Nd_0.05TiO₃ layer by a PLD method. The Ni, Nd-STO, and YBCO layers were confirmed to be biaxially orientated. The resistivity at 77 K between the YBCO layer and the Cu tape was measured to be 0.77 Ω · cm. The Jc of the YBCO layer will be also reported.
