![عکس صفحه اول مقاله: The giant linear magnetostriction in elastic ferromagnetic composites within a porous matrix The giant linear magnetostriction in elastic ferromagnetic composites within a porous matrix](/preview/png/1805332.png)
In this article, a method of producing elastic ferromagnetic composite containing particles of chemical pure iron with sizes of 0.10–0.15 mm was described. The particles were dispersed in an elastic matrix of an elastic silicone rubber. The filling factor of composite by ferromagnetic particles and porous factors were changed in the range from 0.15 to 0.45. The samples of the obtained composite were placed in the magnetic field with induction of 0–8 T, produced by the Bitter-type magnet. The longitudinal magnetostriction of samples was measured by using a coaxial capacitor with a movable plate. It was found that the maximal relative elongation of samples was 4.81% and hysteresis of magnetostriction and also remanent magnetostriction amounted to 1.08%. A slow decay of remanent magnetostriction up to 0.14% in 105 s was also observed.
