- Аннотация: Magnetic properties of the elastomers with hard magnetic particles were investigated by static and dynamic methods. Dynamic measurements (nondiagonal components of the susceptibility tensor) were made by measuring parameters of RLC-components of a coil with a core made of the elastomer with the immitancemeter (AM-3016) at the room temperature. For magnetostatic measurements (diagonal components of the susceptibility tensor) Vibrating Sample Magnetometer LakeShore (7400 System) was used. Components of the susceptibility tensor were of different field dependencies (Figure 1, 2). The demagnetization factor was taken into account. Differences of the elastomer properties with conductive and nonconductive magnetic filler were analyzed. It was found that for the elastomer with non-conductive barium ferrite particles the decrease of the susceptibility obtained by static method was 98 % and by dynamic method 61 %. For the elastomer with conductive NdFeB particles it was 92 % and 58 % respectively, that is close to the above mentioned values (Table 1). In zero field the value of susceptibility of the NdFeB based elastomer exceeded an order of magnitude the susceptibility of the elastomer with barium ferrite particles. Magnetic properties of the composite system were changed non-additive way compared with the properties of the initial magnetic powder. The influence of the interparticle interaction and the elastic properties of the matrix on the system behavior was studied.
