摘要：

Monodisperse ZnFe2O4 nanoparticles were synthesized by polyol process using triethylene glycol as solvent and iron acetylacetonate and zinc acetylacetonate as precursors. The structure, morphology and magnetic properties of resultant particles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM). The results show that as-synthesized nanoparticles have uniform size and good dispersibility. The average size of the nanoparticles is 5.6 nm. The monodisperse ZnFe2O4 nanoparticles show a typical magnetic hysteresis loop at room temperature (300K), which indicates that the sample has ferrimagnetic behavior with less residual magnetism, coercive force of 9355A/m at room temperature. The saturation magnetization of the nanoparticles at 300 K is determined to be 18.10A·m2/kg. The temperature rise of the suspension of 50 mg and 100 mg samples in 1mL water can reach up to 22℃ and 30℃ under magnetic field respectively, revealing sufficient magnet-heating ability. © 2016, Beijing Institute of Aeronautical Materials (BIAM).
