Description
We report the Raman spectra of chemically characterized (Bi2-xPbx)Sr2CaCu2O8+y single crystals for 0<x<0.4. Significant modifications of the spectra, becoming more pronounced with increasing x, are noted with respect to the lead-free crystals in the ranges of the 117-cm-1, (460--530)-cm-1, and (630--650)-cm-1 lines. The interpretation of these modifications provides an important confirmation of recent speculations concerning the lattice dynamics of this family of superconductors and the role of lead in modifying their structure and their microstructure
