Abstract—This work is focused on the magnetic response of magnetoactive elastomer (MAE) based on sili-
cone polymer matrices filled with magnetic particles of magnetically hard NdFeB-alloy. Viscoelastic properties
of MAE were studied by the method of oscillation shear. After magnetization in an external magnetic field of
2 T MAE samples demonstrate more than two-time increase in the storage and loss moduli and 25% increase
in the loss factor. Performed study of the damping properties of the materials has shown that the oscillation time
of the pendulum hammering the magnetized sample is in two times shorter than in case of the non-magnetized
sample. Viscoelastic and damping properties of MAE are defined by magnetic interactions between the magne-
tized particles of the magnetic filler.
