A single resistivity heated source was used to deposit a mixture of BaF{sub 2}, Cu, and Y to form precursor films onto MgO substrates held at room temperature. Different heat treatment conditions were applied to study the stability diagram of YBa{sub 2}Cu{sub 3}O{sub 7{minus}x}. It was found that the stability line is shifted toward the higher oxygen partial pressure and lower temperature side of the pure YBCO line in the presence of fluorine and fluorides in the precursor. Films of good quality were obtained when the annealing conditions were in close proximity to this line.
