Summary

High-critical temperature superconducting films of YBCO were prepared on (100) magnesium oxide substrates by a chemical sol gel method. A procedure is described for preparing a superconducting film using acetate compounds dissolved in salicylic or lactic acids in the presence of ethylene glycol. Transport measurements indicated that the onset temperatures of the superconductivity transition occurred between 82 and 95 K. The zero-resistance transition temperature was above the boiling point of liquid nitrogen. The highest critical current density was 2700 A/cm² at 20 K.
