Abstract

Thin superconducting films of the YbBa₂Cu₃O(7-y) (Yb123) and YBa₂Cu₃O(7-y) (Y123), prepared by post-deposition annealing of the metal naphthenates gels spin-coated on MgO(001) substrate, have been characterized by cross-sectional high-resolution electron microscopy and X-ray diffraction. It was found that the c-axis Yb123 films were epitaxially grown on the MgO(001) substrate at the temperature range from 700°C to 775°C in a gas mixture containing Ar and O₂ with the oxygen partial pressure of p(O₂) = 10^-4 atm. In contrast to the Yb123 films, it was found that Y123 films could be derived at a wider temperature range from 750°C to 950°C. Randomly oriented Y123 films were also grown on the MgO(001) substrate besides the majority of in-plane c-axis oriented growth.
