Abstract
A general theory of sound wave absorption in heterogeneous crystalline structures is proposed using the quasi-classical kinetic equation (QKE), and the microscopic dependence of sound wave damping is calculated: γ(ω, ξ*), where ω is the frequency of external sound as a fumction of concentration ξ* of ferromagnetic particles over a wide range of their average diameters (from centimeter to nanoscale).
