摘要：

We have prepared YBa2Cu3O7-y thin films on {100}<001> cube textured Ag tape (CUTE-Ag tape) by metal organic chemical vapor deposition (MOCVD). The obtained films are highly c axis oriented, and the surfaces of the films were smooth. However, the in-plane alignment of the films was not pure four-fold symmetric Then we examined preparation of YBCO films on Y2O3 buffered CUTE-Ag tapes. The Y2O3 layer was deposited by MOCVD and the YBCO films on that layer was c axis oriented with good inplane alignment. Furthermore after the YBCO films growth were terminated, peak of Y2O3 was almost disappeared. me considered that the Y2O3 layer was incorporated into the YBCO film during deposition. We also deposited YBCO films on {110}<001> textured.;Ag tape for which good in plane alignment of YBCO film was expected from the near-coincidence site lattice (NCSL) model. The critical temperature of both YBCO films on the CUTE-Ag tape and on the {110}<001> textured dg tape were T-c(zero)=80K.
