Effects of Ag addition on the epitaxially grown YbBa2Cu3O7 superconductor on a SrTiO3 (100) substrate by the liquid gas solidification process have been investigated. Ag acts as flux and does not incorporate in the oxide formation. Its addition, however, enhances the transport properties resulting from a reduction in film-substrate interaction. Values of Tc(R=0)=90 K and Jc(77 K, H=0)=3×104 A/cm2 can be achieved reproducibly.

    In metalorganic deposition using trifluoroacetates (TFA-MOD), CuO nanocrystallites in calcined film, which influence the critical current density (J[sub c]) of the resulting film, have seldom been considered before. CuO nanocrystallites ripen and grow during the calcining process at 200-250°C...

    We compare the superlattice modulation, microstructure, and epitaxy of Tl2Ba2Ca2Cu3O10 thin films grown on MgO [100] and SrTiO3 [100] substrates by dc diode sputtering. Films grown on MgO were found to be quite clean with the c axis perpendicular to the substrate. However, no in-plane...

    We report, for the first time, growth of thin films of Y-Ba-Cu-O by pulsed laser deposition onto [001] YbFeO3 single-crystal substrates.
