Description
Summary:YBa(2)Cu(3)O/7-delta/ and YbBa(2)Cu(3)O/7-delta/ layers were coated by sol-gel and PLD on Gd/1.91/Er/0.09/O(3) (100% lattice match with Y- and Yb-123) textured buffer layer on Ni substrates. Different thickness of buffer layers and superconducting layer were tried to see the thickness effect on superconducting properties. Buffer layers were prepared with different lattice parameters for Y-123 and Yb-123. Coated conductors were characterized by means of XRD, ESEM and Tc and Jc measurement. Since the perfect lattice match can be achieved between buffer layer and superconducting layer, texture of superconducting film was improved, and consequently critical current density of Y- and Yb-123 were improved.
