Patent ID: 7910521

Claim:
Coated conductor comprising: a biaxially textured substrate; a template buffer layer composed of a material having the general formula RE 2-x B 2+x O 7 with RE being at least one metal selected from La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Y, Tm, Yb, and Lu, with B being at least one metal selected from Zr and Hf and −0.4≦x≦+0.7, wherein the template buffer layer is deposited on said biaxially textured substrate by metal organic deposition and has a thickness of substantially between 50 nm to 200 nm; and a superconductor layer containing YBCO-123 that is directly deposited onto the template buffer layer, wherein the superconductor layer is obtained by hybrid liquid phase epitaxy.
