Abstract
Y-Ba-Cu-O superconducting films having high J c of 6.3×106 A/cm2 at 77 K and T c of 92 K were prepared by metalorganic chemical vapor deposition using a new transport technique with Ba-addition products. This CVD method could realize stable vaporization and smooth transportation of Ba source material due to the increase of the evaporation rate at low sublimation temperatures. Consequently, good reproducibility for preparation of the high J c films (over 106 A/cm2) was achieved.Keywords
