Properties of YBa2Cu3Ox-δ films on textured Ag tapes

Two types of biaxial textured tape, Ag{110}[112] and Ag{100}[001], have been produced by different rolling and recrystallization from a pure (> 99.95%) Ag plate. YBa2Cu3O7-delta (YBCO) films were then prepared on the Ag tapes by use of pulsed laser deposition (PLD). DC transport measurement revealed that die films on Ag(110)(112) tape have a critical current density (J(c)) in the range of 4-6 X 10(5) A/cm(2) (77 K, 0 T), while the J(c) values of YBCO films on Ag(100)(001) tape, prepared under the same conditions, were lower. Accordingly, X-ray diffraction (XRD) produced sharp spots in the pole-figure of YBCO on the Ag(110)(112) tape, which confirms the presence of a texture in the YBCO film. The pole-figure of the YBCO film on Ag(100)(001) did not show a preferred in-plane orientation. (C) 2000 Elsevier Science B.V. All rights reserved.
