Temperature-dependent ultrasound measurements were performed on a two-phased sintered sample of Bi-Sr-Ca-Cu-O. Attenuation anomalies and velocity changes were observed for 10-MHz longitudinal waves around the two superconducting phase transitions. These features of sound behavior at Tc, also observed in other 90-K high-Tc systems, may result from the direct interaction of intrinsic properties of high-temperature superconductors with sound. A spin-phonon interaction is proposed to interpret the acoustic behavior.
