Annotation
The parameter $\zeta$ of spin-phonon coupling is obtained through the analysis of the spin-wave dynamics of magnetic systems. It is shown that the parameter of spin-phonon coupling is greater, the greater the relative electron-ion potential $g_1$, the smaller the exchange correlation radius $r_c$, and the smaller the mass $M$ of ions that form a crystalline lattice.
