The expressions for the energy of the magnetic and elastic subsystems of magnets of different symmetry were presented. The system of dynamic magnetoelastic equations was constructed. The influence of magnetic ordering on the magnitude of the elastic modules of alloys in which the martensitic phase transformations occur in the lattice was estimated. An assessment of the impact of external factors and the aging process on the elastic modules of magnetically ordered materials was provided. The influence of mechanical and thermal cycling on the elastic modules of the Ni-Mn-Ga alloy was considered. It is shown that the process of cycling leads to destabilization of martensitic phase, and to the decreasing of the shear elastic modulus of martensitic phase.
