Abstract

Rheological properties of magnetoactive elastomers with complex composition are studied. Samples of the elastomer consisting of a soft silicon matrix with embedded micron-sized particles of FeNdB and carbonyl iron powder have been magnetized in the uniform magnetic field of varying strength in order to provide different remanence magnetizations. The storage and loss modulus of samples with different geometries have been measured using oscillating rheometry. The possibility of the passive tuning as well as an active control of the rheological properties of prepared elastomers is shown..
