Abstract

The annealing behavior of Ba2YCu3+xO7+y films grown by coevaporation of BaF2, Y and Cu on SrTiO3 has been studied as a function of temperature. Upon annealing at temperatures below 800°C, the phase forming first is Ba2YCu4O8, independent of the starting stoichiometry. Higher temperatures, above approximately 825 ° C are needed for Ba2YCu3O7 to crystallize.
