Influence of frequency increase on magnetic nanothermometer

Considering the requirements of the temperature measurement during magnetic thermotherapy and some transient process, the working frequency of the magnetic nanothermometer needs to be increased. In this paper, the effect of the frequency increase of the applied magnetic field is analyzed from the origin of magnetodynamics. The theoretical models containing relaxation are deduced to compare with the experimental results. The experimental results verify the temperature sensitivity of the magnetic nanoparticles, and show the difference with the simulation results of theoretical models.
