Abstract

We have used a Y358 precursor stoichiometry in sedimentation deposition. The R-T curves and calculated lattice parameters suggest the formation of Y123 phases in the synthesized films. The R-T curves of films annealed at 900°C and 920°C present multiple Y123 transitions, and the calculated lattice parameters suggest that majority of the phases present in the films is the high Tc Y123 phase. The film annealed at 940°C presents a single phase transition and its crystal structure approach a tetragonal structure. Lattice strain is observed, as evidenced by the decrease in c and V despite the decrease in Tc, which indicates that the grain orientation is influenced by the substrate at this temperature.
