It is shown that in external magnetic fields, a uniaxial magnetic anisotropycomes into being in a magnetoactive elastomer (MAE). The magnitude of theinduced uniaxial anisotropy grows with the increasing external magnetic field.The filler particles are immobilized in the matrix if the MAE sample is cooledbelow 220 K, where the anisotropy can be read out. The cooling of the sample isconsidered as an alternative methodological approach to the experimentalinvestigation of the magnetized state of MAEs. The appearance of magneticanisotropy in MAE is associated with restructuring of the filler duringmagnetization, which leads to an additional effective field felt by themagnetization. It is found that the magnitude of the effective magneticanisotropy constant of the MAE is approximately two times larger than itseffective shear modulus in the absence of magnetic field. It is proposed thatthe experimentally observed large (about 40) ratio of the magnetic anisotropyconstant of the filler to the shear modulus of the matrix deserves attentionfor the explanation of magnetic and magnetoelastic properties of MAEs. It maylead to additional rigidity of the elastic subsystem increasing the shearmodulus of the composite material through the magnetomechanical coupling.
