Abstract

Thin films of high-temperature superconducting materials in the Y-Ba-Cu-O system have been prepared via a novel aqueous solution, using glycine as a complexant. A principal advantage is that no precipitation occurred during initial drying steps, yielding a clear, glass-like material. Film were spin-coated onto SiO 2, Al 2O 3, MgO, and (Y,Zr)TiO 3-coated SiO 2. SIMS compositional depth profiles showed that barium segregated to the interface of SiO 2 and Al 2O 3 substrates, which severly affected the film stoichiometry. Such problems were less pronounced with MgO or (Y,Zr)TiO 3-coated SiO 2 substrates. While superconducting properties have not been optimized, the method holds promise for inexpensive preparation of a wide range of thin film compositions.
