• Polarized Raman spectra of (Sm.z.Ce.7,).(Ba.7.Sm.z,).Cu,0, with the Cu-0,pyramid structure have been measured at room temperature using single crystals.Peaks have been observed at 450 and 525 cm ' in the A.. symmetry configuration andat 200 cm ' in the B.. configuration. A peak due to a Raman-forbidden mode hasbeen observed at 560 cm '. The B.. symmetry peak is assigned to the out-of-phasebending of oxygen in the Cu-0. plane. The energy of this mode is much lower thanthat of YBa.Cu.0. (330 cm '). On the other hand, the energies of the A..-symmetrypeaks are nearly the same as those in YBa.Cu,0. (440 and 500 cm '), suggesting thatthese two peaks are associated with the vibrations of apical oxygen.
