The evidence is reported for enhancement of critical current densityJcin YBa2Cu3O7−&dgr;thick films with the addition of Ag, which is correlated with improvements in structural properties. An improvement of 50% inJc(up to ∼500 A/cm2atT=4.2 K) was obtained in films made from YBCO+60wt % Ag powder, fabricated by the spin‐on technique on (100) SrTiO3, which is correlated with improvements in structure. The resulting films are 10 &mgr;m thick, uniform, partially textured, and show good adherence. The critical temperatureTcis improved by the addition of Ag, and a reduction in the density of microcracks and in the amount of secondary phases in the sintered films was observed. Normal‐state resistivity is reduced by almost three orders of magnitude, making these films potentially useful for electronic applications in interconnects and novel hybrid circuits.
