• 論文の詳細を見る

• The Brillouin scattering in Ca_2Sr(C_2H_5CO_2)_6 have been studied using Fabry-Perot interferometer. The observed Brillouin shifts for different phonon directions have been assigned to specific modes of vibration. From algebraic expressions for the velocities, six elastic constants at 23℃ have been calculated for the hypersonic region. The determined values of elastic constants in units of 10^<10> dyn/cm^2 are C_<11>=11.6, C_<33>=10.1, C_<44>=3.47, C_<12>=6.66, and C_<13>=5.49. The temperature dependence of the Brillouin shift has been studied with particular emphasis on the region close to the Curie temperature. These results are compared with those in the ultrasonic region.
