Description
We have prepared thick films of high T/sub c/ superconductors on a variety of substrates: SrTiO3, BeO, Zr(Ca)O2, alumina, and sapphire. The powder of the YBa2Cu3O/sub 7-δ/ compound is mixed with an organic solvent and painted on the substrates. The films are then dried and fired. We have studied the effect of the substrate and of the firing temperature on the superconducting properties of the films. We found an optimum firing temperature of 990 degree C. The films prepared are superconducting with T/sub c/ (R=0) as high as 82 K. We discuss the shape of the resistance-versus-temperature curves as well as the temperature dependence of the critical currents of these films
