Abstract
High Tc Y1−x Yb x Ba2Cu3O7−y films were prepared on SrTiO3(100) substrates by chemical vapor deposition method. Yb1Ba2Cu3O7−y films were obtained at higher oxygen partial pressure compared with Y1Ba2Cu3O7−y films at the same deposition temperature. Tc,o (R=0) decreased about 1.5 K when Y was fully substituted with Yb. The caxis lattice parameter of Y1−x Yb x Ba2Cu3O7−y films also decreased as the amount of Yb(x) increased.
