Abstract

Raman scattering spectra of Sr_14-xCa_xCu₂₄O₄₁ (x = 0 and 11.5) have been measured. In the (a,a), (b,b), and (c,c) spectra, the intra-molecular vibrations for the ladders (Sr/Ca)₂Cu₂O₃ and the 1D chains CuO₂ have been clearly observed below 700 cm^-1. By comparing the number of the observed peaks with the results of the factor group analysis, the crystallographic symmetry of the ladder is F₂₂₂ for both the x, while that of the chain changes from A_mma to F₂₂₂ with increasing x. From the results of the pressure dependence for x = 0, it can be inferred that the lifetime of phonons decreases with increasing applied pressure.
