Abstract

Efficient heating of magnetic nanoparticles by means of the ferromagnetic resonance method is demonstrated with the use of isotropic superparamagnetic nickel ferrite powder as an example. The kinetic heating curves ΔT(t) were measured at frequency of f=8.9GHz. It is shown that the obtained ΔT values are fairly well described by theoretical expressions for the absorption of microwave energy in an isotropic superparamagnet. This imparts some basic quantification to the idea of magnetic hyperthermia that operates in the ultra-high frequency range.
