Abstract

YBa2Cu3O7-delta and YbBa2Cu3O7-delta layers were coated by sol-gel and PLD on Gd1.91Er0.09O3 (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 T-c and J(c) 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.
