摘要：

The development and characterization of a new substrate material Ba2EuNbO6 for YBCO films: are reported. Ba2EuNbO6 has a complex cubic perovskite structure [A(2)(BB')O-6] with a lattice constant a = 8.455 Angstrom. The dielectric constant and loss factor of this material are in a range suitable for its use as a substrate material for microwave applications. Superconducting YBCO-Ag thin films have been grown in situ on polycrystalline Ba2EuNbO6 by pulsed laser ablation technique and the optimum growth conditions have been established. The films exhibited (00l) orientation of a YBCO orthorhombic phase and gave a zero resistivity superconducting transition at T-c(0)= 90 K with a transition width of 1.5 K.
