The effect of magnetic anisotropy on magnetic properties of ferrite nanoparticles synthesized by wet chemical precipitation method

The magnetic hyperthermia is one of the efficient and newapproaches for cancer treatment. Where the magnetice nanoparticles as heat sources are used to destroy cancer cellsAmong. different factors, the magnetic anisotropy is one of the most important parameters which strongly affect the magnetic properties and hyperthermia output of a system of nanoparticles. Therefore, in this study, we first investigated the effect of Co-doping on the structural, morphology and magnetic properties of xCoFe 3-xO4 samples. In the next section of this work, we studied the hyperthermia properties. The resultes shown that the heat efficiency of the samples does not change significantly. Because of increasing the Cobalt content and hence increasing magnetocrystalline anisotropy in the samples, this was an unexpected result.
