Abstract
The effect of structural defects on the critical ultrasound absorption and ultrasound velocity dispersion in Ising-like three-dimensional systems is studied. A field-theoretical description of the dynamic effects of acoustic-wave propagation in solids during phase transitions is performed with allowance for both fluctuation and relaxation absorption mechanisms. The temperature and frequency dependences of the scaling functions of the absorption coefficient and the ultrasound velocity dispersion are calculated in a two-loop approximation for homogeneous and structurally disordered systems, and their asymptotic behavior in hydrodynamic and critical regions is separated. As compared to a homogeneous system, the presence of structural defects in it is shown to cause a stronger increase in the sound absorption coefficient and the sound velocity dispersion even in the hydrodynamic region as the critical temperature is reached. As compared to homogeneous analogs, structurally disordered systems should exhibit stronger temperature and frequency dependences of the acoustic characteristics in the critical region.
