Specifying the ferrofluid parameters important from the viewpoint of magnetic fluid hyperthermia

摘要

The article presents the experimental study of magnetic fluid hyperthermia (MFH) utilizing magnetite nanoparticles with diameter of 15.2 nm. Temperature measurements of the ferrofluid samples were carried out in real measurement system using parallel resonance phenomenon. Based on the obtained temperature curves the basic heating parameters of ferrofluid, namely the Specific Absorption Rate (SAR) and power losses in tested nanoparticles have been specified. The authors systematize the current knowledge of these quantities and additionally propose two models that simplify their determination with given errors, omitting the mass and volume concentrations of the individual components of magnetic fluid.
