  • Abstract
    YBa2Cu3O7-δ films have been prepared by spin-coating solutions of metal acetates dissolved in trifluoroacetic acid/methanol and trifluoroacetic acid/isopropanol/1,3 propanediol onto LaAlO3(100) substrates. By using a rapid, low pO2 pyrolysis process, high-quality diol films (0.25 μm thick) with Jc values as high as 14 MA/cm2 and 2 MA/cm2 at 7 K and 77 K, respectively, were fabricated in one tenth the time, compared to conventional processing schemes. The effect of multicoating, in order to reach YBCO film thicknesses of 1.5 μm, on the Jc was also studied
