Ultrasonic waves in magnetic liquids: Two-phase approach and experimental results

A two-phase model of dynamical behavior of magnetic liquid influenced by co nstant magnetic field is considered. The model takes into account mutual in teraction of clusters giving skeleton's stiffness and interaction of cluste rs with free liquid producing attenuation and dispersion of waves for trans versally isotropic system. Rotational degrees of freedom are disregarded. P redictions of the model are discussed for variable amount of clusters and c ompared with experimental data for different magnetic fields.
