摘要：

YBa2Cu3O7-delta films have been prepared by spin-coating solutions of metal acetates dissolved in trifluoroacetic acid/methanol and trifluoroacetic acid/isopropanoyl/1,3 propanediol onto LaAlO3 (100) substrates. By using a rapid, low pO(2) pyrolysis process, high-quality diol films (0.25 mum thick) with J(c) values as high as 14 MA/cm(2) and 2 MA/cm(2) 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 mum, on the J(c) was also studied.
