Abstract :
The expression for magnetoelastic energy density of saturated ferromagnetic dielectric with cubic symmetry has been theoretically analyzed. Mechanical stress induced changes of magnetocrystalline anisotropy constants have been derived, based on 3-parametric anisotropy model. An experimental radiospectroscopic method of magnetoelastic coupling coefficients determination has been suggested.
