Abstract

We present results of Raman scattering studies of superconducting YBa₂Cu₃O_7-x(YBCO) films grown by chemical vapor deposition and metal-organic deposition methods. It is shown by X-ray diffraction that all the as-grown YBCO films have a highly c-axis oriented and in-plane aligned texture. Raman scattering measurements were used to investigate optical phonon modes, oxygen contents, structural properties, and second-phases of the YBCO coated conductors. Raman spectra of YBCO films with lower-transport qualities exhibit additional phonon modes at ∼300 cm^-1, ∼600 cm^-1, and ∼630 cm^-1, which are related to second-phases such as Ba₂Cu₃O_5.9 and BaCuO₂. Our results strongly suggest that Raman scattering be useful for optimizing YBCO film growth conditions.
