【 摘 要 】

In the YBa2Cu3O7-xcoated conductor, the buffer layer is crucial for the texture transfer from the Ni-5%W substrate to the superconducting layer. We developed original La2-xGdxZr2O7buffer layers (x ≤ 1) by chemical solution deposition to decrease the structure mismatch between the substrate and the buffer layer. They show a strong cube texture up to the surface, a crack free surface and a very low roughness. In conclusion, the La2-xGdxZr2O7layers with 0.4 2Zr2O7buffer layer.
