Abstract

We present results of a Raman scattering study of Bi₂Sr₂CaCu₂O₈ single crystals with T_c equals 95 K in a wide temperature (65 - 365 K) and frequency (from 640 down to 10 cm^-1) range. The features due to superstructure modulation are found in the low-frequency range. We also investigated additional lines seen in z(xx)z and z(yy)z scattering configurations in the regions of 160 - 240 cm^-1 and 300 - 450 cm^-1 and analyzed the temperature dependence of the latter.
