Validity limits of the Néel relaxation model of magnetic nanoparticles for hyperthermia.
The derivation of the optimum mean diameter of magnetic nanoparticles (MNP) for hyperthermia as a tumour therapy in the literature is commonly reduced to application of the Néel relaxation model. Serious restrictions of this model for MNP for hyperthermia are discussed and a way is outlined to a more comprehensive model including hysteresis.
