Abstract

The Y-Ba-Cu-O film prepared by chemical vapor deposition showed T c=91.5 K and Bc2 (77.3 K)=60 T defined by zero resistance. The Jc values measured at 77.3 K were 7.8×105 A/cm2 at B=0 and 1.0×105 A/cm2 at 16 T, magnetic fields perpendicular to the c axis. Small disk-shaped precipitates possibly regarded as strong flux pinning centers in the Y-Ba-Cu-O films were observed using transmission electron microscopy. The evaluation of Jc related to the concentration and configuration of the precipitates was in reasonable agreement with the measured Jc values.
