Description

High-T/sub c/ superconducting Y1Ba2Cu3O/sub 7-//sub x/ bulk samples were prepared by polymeric precursor synthesis. Resistance, x-ray diffraction, and Raman scattering measurements were performed for sample characterization. The bulk specimen exhibited a sharp superconducting transition at 94.5 K with a 10%--90% transition width of 0.5 K. Four Raman active phonon modes were observed at frequences of 150, 337, 440, and 502 cm-1 in the 120--700 cm-1 region
