Abstract

A critical review of models for the dynamics of interacting magnetic nanoparticles is given. It is shown that the basic assumptions in the Dormann-Bessais-Fiorani model are unrealistic. The experimental observations on systems of interacting magnetic nanoparticles can, at least qualitatively, be explained by the model derived by Mørup and Tronc for weakly interacting particles, in combination with a transition to an ordered state in the case of strong interactions.
