SrTiO 3 (STO) thin film was prepared on single crystal MgO (100) substrate by rf magnetron sputtering as a buffer layer of superconducting thin film. Sputtering conditions influence to the structural property were investigated. Highly epitaxial a-axis oriented STO thin film with extremely smooth surface was obtained by optimizing the sputtering parameters. YBa 2 Cu 3 O 7-δ (YBCO) thin film with critical temperature (T c ) of 89.8 K was obtained on STO buffer. Surface morphology of YBCO thin film was also improved. The effects of STO buffer were discussed in comparison with YBCO thin films on MgO substrate.

Noise Spectral Density

1/f noise experiments performed on Y 1 Ba 2 Cu 3 O 7−δ single crystals indicate that (1) the normalized noise spectral density Sυ/V2 is much larger than that of metals; (2) the temperature dependence of Sυ/V2 differs from that of the resistivity; and (3) in the superconducting transition region, the behavior of 1/f noise is distinct from that observed in bulk and thin film copper oxide systems. Possible explanations for these observations including the important role played by the crystal morphology are discussed.
