The Raman spectrum from 10 to 550 cm/sup -1/ has been obtained from the Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub 8+//sub y/ superconductor. Modes similar to those exhibited by YBa/sub 2/Cu/sub 3/O/sub 7-//sub y/ are found, as expected from similarities in the crystal structures of the two materials. In addition, several strong low-frequency modes are present, suggestive of a material with loosely coupled substructures consistent with the structural x-ray analysis of Bi/sub 2/Sr/sub 2/CaCu/sub 2/O/sub 8+//sub y/. Meissner analysis shows that the sample used exhibits bulk superconductivity.
