Abstract
The purpose of this work was to research the influence of interparticle interactions, the elastic properties of matrix and the method of particles preparation on the magnetic properties of the magnetoactive elastomers based on polyurethane rubber containing magnetic particles with high coercivity both conducting and non-conducting. Magnetostatic properties measurements of magnetoactive elastomers were carried out using Vibrating Sample Magnetometer. The diagonal components of susceptibility tensor were found. The dynamic magnetic susceptibility (non-diagonal components) of magnetoactive elastomers was found with immitance-meter using a coil with an elastomeric core. The measured static and dynamic parameters of different samples were compared with each other. Mechanisms of magnetization changes in parallel and crossed magnetic fields are discussed.
