In this study, the self-organization and the heat generation of ferromagnetic nanoparticles subjected to a radio frequency alternating magnetic field were investigated numerically and experimentally aimed at application to magnetic hyperthermia for cancer therapy. It was found that ferromagnetic nanoparticles formed clusters under an ac magnetic field and the heat generation efficiency of the nanoparticles was varied depending on the cluster structures. The dependence of the cluster structures and the amount of heat generated by the nanoparticles on the experimental parameters such as the amplitude of the ac magnetic field and the volume fraction of the nanoparticles was analyzed and the effect of the cluster formation on the heat generation efficiency of the nanoparticles was clarified.
