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.

Barium erbium niobate (Ba2ErNbO6) has been developed as a new substrate for (Bi,Pb)2Sr2Ca2Cu3O𝑥 [Bi(2223)] superconductor film. Ba2ErNbO6 (BENO) has a cubic perovskite structure with lattice constant, 𝑎 = 8.318 Å. The Bi(2223) superconductor does not show any detectable chemical reaction with BENO even under extreme processing conditions. Dip coated Bi (2223) thick film, Ba2ErNbO6 substrate, gave a 𝑇c (0) of 110 K and current density of ∼ 4 × 103 A cm-2 at 77 K and zero magnetic field.
