Аннотация

The paper presents the results of computer modeling of structure formation in nanodispersed magnetic fluids and the influence of this process on the kinetics of their magnetization reversal. A system of identical spherical single-domain ferromagnetic particles suspended in a Newtonian fluid with magnetic moments “frozen” into their bodies is considered. The particles are involved in intense Brownian motion. The magnetic interaction of all particles with all, as well as with an external magnetic field, is considered.

The results show that the evolution of internal structures with a change in the external field can greatly, by several orders of magnitude, change the characteristic time of magnetization reversal of a ferrofluid. The results obtained can be useful for the development of both the general theory of these systems and many methods of their high-tech application.
