Elastomeric silicone composites with ferromagnetic filler are investigated. The distribution of carbonyl iron filler in the polymer matrix by scanning electron microscopy is visualized. Using atomic force microscopy the magnetostrictive characteristics of these materials are established. 57 Fe nuclei hyperfine parameters of the iron filler atoms in the composites are determined by Mössbauer spectroscopy. The influence of the filler microparticles restructuring in external magnetic fields on the composites properties is discussed. The prospects for creating new materials and devices based on the characteristics of such magnetically active elastomers are revealed.
