Article Preview

In this work are considered new magneto-controlled materials – magnetoelastics, their elastic and magnetic properties. Much attention is devoted to influence of distribution of magnetic particles by their size on these properties. It was found that the application of a magnetic field on magnetoelastics with larger particles leads to a considerable rise of the shear modulus. It was shown that damping of torsional vibrations strongly depends on both value of magnetic field and concentration of large particles. A comparison between shear modulus, obtained from classic method and from torsional vibrations was made and a good coincidence of results was found. It was found out that hysteresis loops for considered polymer materials have unusual character.
