Coated conductor with simplified layer architecture

Coated conductor comprising:na 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; anda 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.
