The results of theoretical and experimental study of surface magnetoelastic waves in two-phase structure of lithium niobate and composite material of the films TbCo / FeCo are presented, possessing properties of giant magnetostriction. The effective parameters model of the magnetostrictive materaial is developed. Dependence of the dispersion on the applied magnetic field is obtained and analysed.
