Abstract
Abstract The physico-mathematical model of collective mechanical and magnetic dynamics of Stoner-Wohlfarth particle couple in liquid with regard to interparticle dipole-dipole and hydrodynamic interaction was developed. It is demonstrated that hydrodynamic interaction leads to formation of rigid doublet, and we also presented the results of numerical study of dipole-dipole interaction influence on magnetic reversal featured as well as on dynamic magnetic hysteresis and alternating magnetic field energy absorption by rigid doublet in solid and liquid suspension. It is demonstrated that taking into account the physiological limitation of amplitude and frequency of the field, the dipole-dipole interparticle interaction does not affect the energy dissipation, but changes the field parameters necessary to achieve the maximum specific absorption rate.
