N2 - We have deposited Y2O3 buffer layers by metal-organic chemical vapor deposition (MOCVD) on textured Ni tapes coated with biaxially aligned NiO(1 0 0) layers grown by surface oxidation epitaxy method. X-ray diffraction measurements showed that Y2O3 grew cube-on-cube on NiO layer, i.e. it has also biaxial orientation. With these Y2O3 layers, in-plane aligned YBa2Cu3O7-δ (YBCO) (0 0 1) thick films (∼3 μm in thickness) have been successfully grown by liquid phase epitaxy (LPE) method on the textured Ni tapes. YBCO seed layers, required in LPE process, had been also deposited by MOCVD. The LPE-grown YBCO thick films exhibit superconductivity transition temperature of Tc, onset = 90 K and Tc, zero = 65 K by four-probe transport measurement.
