Abstract

Abstract The fact of the existence of temperature dependence of acoustic attenuation anisotropy in a very broad temperature region for crystals with cubic paraphase has been established. It has been shown that in KTa03:Li crystal the anisotropy is assosiated with the great distinction of the sound order-parameter coupling constants. For SrTi03 crystal the anisotropy anomaly originates from strongly anisotropic quasi-two-dimension character of the order-parameter fluctuations.
