Abstract

We present the results of mathematical modeling and theoretical study of the magnetic hyperthermia effect in a system of ferromagnetic nanoparticles, united in two-particle aggregates. The heat effect is produced by a linearly polarized oscillating magnetic field. The influence of the coupling of the particles on the thermal effect is analyzed. The results show that particle aggregation decreases the hyperthermia effect.
