This paper reports on thin films of the high-temperature superconductor Y{sub 1}Ba{sub 2}Cu{sub 3}O{sub 7{minus}x} grown {ital in situ} by ion beam sputtering from metal binary alloys. The metal binary allows used were YCu and BaCu. The correct composition of the deposited film was obtained adjusting the position of the targets with respect to the ion beam. The films were deposited onto heated SrTiO{sub 3} substrates in oxygen partial pressure. After deposition the samples were slowly cooled to room temperature with a short step at 450{degrees} C. The films did not need any further annealing after deposition and showed superconducting properties.
