A new high-T _c superconducting cuprate composed of Ba, Cu and O was prepared on SrTiO₃(001) substrate by reactive coevaporation. The superconducting phase is formed only in the limited temperature range between 575 and 625^° C and in a narrow compositional range. Observations of the X-ray diffraction and transmission electron microscopy suggests that the superconducting phase is the 214-based structure. Superconductivity is obtained only after strong oxidation after film growth. The resistivity measurement shows T_c^onset≈ 60 to 70 K and T _c ^end=< 38 K and the magnetic measurement shows T_c^onset≈ 85 to 90 K.
