摘要：

Thin-film composites of co-sputtered Y1Ba2Cu3O7-x and LaAlO3 have been deposited by off-axis magnetron sputtering. Scanning electron microscopy (SEM) and x-ray diffraction studies suggest that LaAlO3 precipitates along the grain boundaries of the Y1Ba2Cu3O7-x grains. The normal state conductivity, transition temperature, and critical current density systematically decreased with increasing LaAlO3 composition, consistent with a decrease in the coupling between Y1Ba2Cu3O7-x grains. Inductive transition widths were only a few degrees wide for all LaAlO3 compositions, indicating homogeneous materials. Initial photoresponse measurements show bolometric behavior near T(c) and increased response for greater LaAlO3 compositions.
