The giant magnetostriction in ferromagnetic composites within an elastomermatrix

The way of production and the magnetostriction investigation of ferromagnet ic composites within an elastomer matrix are described in this paper. The p roduced composites consisted of silicon steel particles of 0.15-0.20 mm in size and filling factor 0.4, 0.6, and 0.8, dispersed in the silicone matrix . The investigation of these composite samples was carried out in a homogen eous magnetic field with the range of 0-8 T produced through Bitter's magne t. The giant magnetostriction of order 10(-2), its fast increase similar to the burst effect, and the magnetostriction hysteresis were found in this i nvestigation.
