Abstract
NixZn(1-x)Fe2O4 (x = 0.4, 0.6, 0.7, 1) nanocrystalline powders were synthesized by using a modified spraying-coprecipitation method. The spraying-coprecipitated precursors of NixZn(1-x)Fe2O4 were heated to form ferrites with different particle sizes. The particle size of the NixZn(1-x)Fe2O4 powders gradually decreased with increasing content of Ni. Due to small size effect and orientation polarization, the sample Ni0.7Zn0.3Fe2O4 exhibited an RLmin of −64.37 dB at 6.48 GHz, as the thickness was 5.91 mm. Meanwhile, it had an effective absorption frequency range of 3.6 – 7.44 GHz and a bandwidth of 3.84 GHz, covering almost the C-band. Therefore, the NixZn(1-x)Fe2O4 powders synthesized in this way are promising microwave absorbing materials.
