摘要：

The present paper was written with the aim of synthesizing zirconium ferrite nanopowders and evaluating its magnetic hyperthermia properties. A mechanical milling process along with a sintering process were conduct on the raw powders to prepare zirconium ferrite nanopowders. Xray diffraction results confirmed a pure product and the VSM tools, showed a single domain state for the powders with a size less than 35 nm. Analysis of the samples under AC magnetic field demonstrated that mono-disperse nanoparticles met a higher value of the specific absorption rate (SAR) in comparison with multi-disperse one. Besides, according to the linear response theory the ratio of the anisotropy energy to the thermal one, as a dimensionless anisotropy parameter (sigma), has a key role in the SAR values of zirconium ferrite nanopowders.
