    • Abstract

       

      A complex perovskite oxide, YbBa2NbO6, as a non-reacting substrate for YBa2Cu3O7–𝛿 superconducting film has been developed. The dielectric constant and loss factor values of the material are in the range suitable for its use as substrate for microwave application. A YBa2Cu3O7–𝛿 superconducting thick film dip coated on YbBa2NbO6 substrate gave a 𝑇c (0) of 92 K and current density of ∼ 1.3 × 104 A cm-2.
