Abstract

Dynamical spin fluctuation and lattice vibration in Bi-Sr-Ca-Cu-O single crystals with T _c=80 K is investigated by Raman scattering. Very broad scattering, ranging from low energy to over 4000 cm^-1, is observed together with more than ten phonon peaks. Very broad scattering is assigned to the two-magnon scattering from the overdamped spin fluctuation on the two-dimensional Cu-O layers as in the case of superconducting (La_1-xSr_x)₂CuO₄ and YBa₂Cu₃O_7-y.
