- Аннотация: The multiferroic materials are of great interest now. Magnetoelectric effect in multiferroic composites consisted of ferroelectric and ferromagnetic components is the result of mechanical connection between components and magnetostriction and piezoelectric effects. The multilayer multiferroic composites are studied mostly. At the same time magnetorheological (magnetoactive) elastomers are so-called “smart” materials. The different parameters of composites based on elastomer polymers are tunable by magnetic field. Young’s modulus, deformation and other mechanical parameters can be changed by magnetic field up to 1000%. The dielectric permittivity also can be changed in magnetic elastomers by magnetic field – magnetodielectric effect (MDE) [1]. It is assumed that the increasing of permittivity of the elastomer in the external magnetic field is due to the rotation of the magnetic moment of the filling particles and their displacement in the elastic matrix. Thus, the displacement of magnetic particles leads to internal stresses in the elastic matrix. The combination of ferromagnetic and ferroelectric filling particles can lead to new material, which properties can be changed by external both electric and magnetic fields.
