Description
Neutron scattering measurements were performed on polycrystalline Y-Ba-Cu-O ceramics to explore the relationship between structure, vibrational density of states and superconductivity. The experiment was made on three powder samples of YBa2Cu3Oy. Neutron diffraction data were usedto determine the structure and oxygen content by Rietveld refinement. The inelastic scattering spectra were obtained on the HET spectrometer at the ISIS neutron source. The vibrational density of states spectra were recorded for each sample at different temperatures. A V3Ge A-15-type superconductor was used for comparison. (author) 6 refs.; 2 figs
