Abstract
A coated conductor with simplified layer architecture includes a biaxial textured substrate, a template buffer layer composed of a material having the general formula RE2−xB2+xO7 with RE being at least one lanthanoid metal, B being at least one metal selected from Zr and Hf and −0.4≦x≦+0.7, where the superconductor layer is obtainable by hybrid liquid phase epitaxy and can be deposited directly onto the template buffer layer.
Claims5
Coated conductor comprising:
- a biaxially textured substrate;
- a template buffer layer composed of a material having the general formula RE2-xB2+xO7 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.
