Description
Single crystals of superconducting Ba2MCu3O/sub x/ (M = Y, Gd) have been used for a study of the polarization dependence of the Raman spectra so as to better understand the lattice dynamics and the role of O defects in these materials. Several prominent vibrational bands have strong polarization dependence and can all be attributed to specific modes with A/sub g/ symmetry. Broad features between 500 and 600 cm/sup -1/ are suggested to be related to O vacancy disorder
