Abstract

Raman scattering data from superconducting phases of SmBa₂Cu₃O_x subject to different heat treatments are reported and compared with those of the impurity phase BaCuO₂. It is found that the high frequency 640 cm^-1 mode corresponds to a characteristic vibration within the superconducting phase. Its sensitivity to heat treatment conditions and to oxygen content suggest an assignment of the mode to the Cu(1)O(1) stretching vibration.
