The Raman spectrum from 10 to 550 cm-1 has been obtained from the Bi2Sr2CaCu3O8+y superconductor. Modes similar to those exhibited by YBa2Cu3O7-y are found, as expected from similarities in the crystal structures of the two materials. In addition, several strong lowfrequency modes are present, suggestive of a material with loosely coupled substructures consistent with the structural x-ray analysis of Bi2Sr2CaCu3O8+y. Meissner analysis shows that the sample used exhibits bulk superconductivity.
