Abstract

Y1Ba2Cu3O7-x superconducting composites have been prepared on metallic substrate by rf magnetron sputtering method. Buffer layer of thin SrTiO3 layer between superconducting film and the substrate was found to be effective to realize superconductivity. Preferable grain alignment of c-axis was also obtained. The critical current density at 77K was 2.2x103 A/cm2 with Tc at 83K, and it was found that the thicker films had the higher Jc values.
