Abstract
YBa2Cu3O7-x films were deposited by spraying an aqueous solution of Y + Ba + Cu nitrates on heated polycrystalline Al2O3 and SrTiO3 single crystal substrates. The spray technique permitted the preparation of YBa2Cu3O7-x with a Tonset of about 90 - 92 K and the completion of superconductivity at a Tzero of 70 - 77 K. Different deposition parameters were studied and the YBCO films were characterized using SEM, Raman spectroscopy, X-ray diffraction and electron microprobe techniques.
