抄録

We have successfully fabricated YBa₂Cu₃O_y (Y123) and GdBa₂Cu₃O_y (Gd123) films on SrTiO₃ substrates by the ex situ heat treatment of co-evaporated Y-BaF₂-Cu and Gd-BaF₂-Cu precursor films prepared by electron beam deposition technique without water vapor. T_c and J_c of the Y123 film were 91.6 K and 0.95 MA cm^-2 at 77 K at self-field, respectively. The Gd123 film showed T_c of 93.4 K and J_c of 1.5 MA cm^-2 at 77 K at self-field. It was found that the surface morphology of the Y123 and the Gd123 films depended on the partial oxygen pressure during the heat treatment.
