Abstract
The paper deals with the theoretical study of the effect of chain-like aggregates on the diffusion of magnetic particles in ferrofluids. Our analysis shows that the appearance of the chains leads to strong anisotropy of the diffusion transport—the diffusion coefficient in the direction of an applied magnetic field is significantly more than that in the perpendicular direction. Effects of the interchain interaction are taken into account.
