Abstract

Nanosized Co_0.5Zn_0.5Fe₂O₄ ferrite was prepared by chemical co-precipitation method. The samples were characterized by X-ray diffraction (XRD), field-emission transmission electron microscopy (FETEM), vibrating sample magnetometer (VSM) and network analyzer. TEM analysis indicates that the diameter of as-prepared powder is about 20–30 nm. The saturation magnetization of nanosized Co_0.5Zn_0.5Fe₂O₄ ferrite is 74.01 mA·m²·g⁻¹. The complex permittivity and complex permeability of the Co–Zn ferrite were measured by vector network analyzer in the frequency range of 2.0–18.0 GHz, and the reflection loss (RL) was investigated according to the wave transmission theory. The results show that the maximum reflection loss reaches −13.7 dB at 6.8 GHz and the bandwidth of reflection loss less than −10 dB reaches 3.8 GHz. The as-prepared nanosized Co_0.5Zn_0.5Fe₂O₄ ferrite can be potentially used as an excellent microwave absorber in the C-band.
