摘要：

All the elastic stiffness constants in the I and II phases of Ca2Sr(C2H5CO2)6 were determined in an ultrasonic frequency region in the temperature range from —80°C to 70°C. The anomalies in the velocities of the longitudinal modes show the logarithmic divergence above the I–II phase transition temperature, whereas the velocities of the transverse modes show no anomaly in the I phase. These phenomena can be well explained by the Levanyuk-Dvořák theory of the nonpiezoelectric material. © 1979, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
