The multiferroic ferroelectric-ferromagnetic-polymer composite systems, consisting of ferroelectric PZT particles, ferromagnetic NdFeB (or barium ferrite) particles, and silicone matrix, were investigated. The influence of the polymer Young's modulus on the properties was determined. The coercivity of elastomers with the same magnetic fillers in different matrices differs by a factor of 7. The influence of magnetic field on electric properties was investigated. Magnetodielectric effect in three-phase samples was found to be non-monotonic. The influence of electric field on magnetic properties of elastomers was investigated. The magnetoelectric effect under an applied electric field in new three-phase material was discovered.

Abstract
The multiferroic ferroelectric-ferromagnetic-polymer composite systems, consisting of ferroelectric PZT particles, ferromagnetic NdFeB (or barium ferrite) particles, and silicone matrix, were investigated. The influence of the polymer Young's modulus on the properties was determined. The coercivity of elastomers with the same magnetic fillers in different matrices differs by a factor of 7. The influence of magnetic field on electric properties was investigated. Magnetodielectric effect in three-phase samples was found to be non-monotonic. The influence of electric field on magnetic properties of elastomers was investigated. The magnetoelectric effect under an applied electric field in new three-phase material was discovered.
