Summary: Assemblies of magnetite nanoparticles for magnetic hyperthermia were obtained by ultrasonic mechanocavitation in a viscous liquid. These magnetite nanoparticles retained the perfect crystal structure of the original coarse-grained magnetite powder, with sizes ranging from 0.2-8 μm, and exhibited a high saturation magnetization comparable to pure magnetite. The specific absorption rate (SAR) of the assemblies in an alternating magnetic field showed a significant dependence on nanoparticle concentration and the shape of particle macroaggregates. The SAR of elongated clusters of particles oriented parallel to the action of the magnetic field was found to be 4 times higher than that of quasi-spherical clusters. The SAR of elongated clusters also showed a sharp dependence on the direction of the magnetic field with respect to the cluster orientation axis, as revealed by numerical simulations based on the stochastic Landau-Lifshitz equation.

Summary: This concise review discusses the realm of superparamagnetic nanoparticles, particularly focusing on Fe2O3, Mg1+xFe2-2xTixO4, Ni1-xCux, and CrxNi1-x, along with their synthesis methods and applications in magnetic hyperthermia. Significant progress has been made in controlling the size and shape of these nanoparticles through various synthesis techniques such as coprecipitation, mechanical milling, microemulsion, and sol-gel synthesis. The review aims to provide insights into the outcomes of diverse synthesis methods, surface treatment of superparamagnetic nanoparticles, their magnetic properties, and Curie temperature, and elucidate their impact on heating efficiency when subjected to high-frequency magnetic fields.

Summary: Numerical simulations were conducted to study the magnetization dynamics of dilute assemblies of iron oxide nanoparticles under alternating and static magnetic fields. The specific absorption rate (SAR) was calculated depending on the angle between the ac and dc magnetic fields. The spatial distribution of SAR near the field-free point was obtained for assemblies with different nanoparticle size distributions, which could be useful for the development of magnetic nanoparticle imaging and magnetic hyperthermia.
