Paper Abstract

The current state of the Raman spectroscopy of YBa2Cu307_8 (referred to as the Y123 material) is briefly reviewed. The Raman-active Cu-0 stretching modes in the Y123 structure are assigned. The extraneous line at 632 cm 1 which occurs with variable intensity in differently prepared samples appears not to be associated with either the Y2BaCu05 (green) or the BaCuO2 impurity phases. It is probably due to a structural defect in the crystalline grains of the Y123 phase. Preliminary results on thin films of a nominal Y213 composition, on the oxygen-deficient tetragonal Y123 phase and the recently synthesized Y336 phase, are also reported.
