| description | The Ni<sub>0.5</sub>Zn<sub>0.5</sub>Fe<sub>2</sub>O<sub>4</sub> nano absorbing materials were prepared by two-step method(coprecipitation method combined with sol-gel method), and the microwave absorption influence of the calcination temperature of the precursor in sol-gel method were explored. Moreover, the microstructure and electromagnetic properties of the as-prepared samples were characterized by the X-ray diffraction (XRD), atomic force microscope (AFM), vector network analysis (VNA). Consequently, XRD analysis indicates that the pure Ni<sub>0.5</sub>Zn<sub>0.5</sub>Fe<sub>2</sub>O<sub>4</sub> nanoparticles can be obtained while the temperature is higher than 650℃. The AFM results show that the microstructure size of the samples tends to be smaller and more uniform while the temperature is increased. Besides, the VNA results indicate the Ni<sub>0.5</sub>Zn<sub>0.5</sub>Fe<sub>2</sub>O<sub>4</sub> exhibits best electromagnetic properties within 2-12.4GHz at the calcination the temperature is 650℃, and the as-prepared samples possess excellent microwave absorption performance. The qualified absorption bandwidth reaches 4.9GHz, and the maximum reflection loss reaches -24.94dB. |
