Abstract
Composite layers consisting of a YBa2Cu3Oy superconducting ceramic and Ag o r Al-clad substrates are prepared by rolling and pressing. The procedure fo r preparing an Al-clad Cu substrate is described. The superconducting trans ition temperature of the ceramic layers is 89-90 K, and the critical curren t density is j(c) > 10(3) A/cm(2). The j(c) data are correlated with the su rface microstructure of the ceramic layers.
