Nonuniform elastomagnetoelectric effects in a disordered medium

A system of nonlinear equations for the determination of the ground state and the analysis of the possibility of the existence of different elastomagnetoelectric effects in the presence of nonuniform external influences has been obtained by the method of variation of the thermodynamic potential of the disordered medium over the electric and magnetic field strengths and elastic strains. It has been shown that the nonuniform strains created by the gravitational or centrifugal forces can serve as a source of the internal electric fields.
