Description
We report Raman scattering measurements of MBa2Cu3O7 (M Y, Sm, Eu) polycrystalline superconductors in the region of Cu-O stretching vibrations. Four peaks are seen. On the basis of the factor group analysis given here they are assigned to two Raman allowed and two ir-allowed LO modes. The latter are probably induced by disorder (e.g. O-vacancies). (author)
