摘要：

Manganese-doped nano-Ni-Zn ferrites were synthesized by a hydrothermal method. The structure and magnetism of nickel-zinc (Ni-Zn) ferrites and nickel-manganese-zinc (Ni-Mn-Zn) ferrites were characterized by diffraction of X-rays diffraction (XRD), scanning electron microscopy (SEM) and physical property measurement system (PPMS) analysis. Effects of element ratio of Ni-Zn and Ni-Mn-Zn ferrites on the microwave absorption properties was investigated. The results show that the four ferrites are spherical-like with relatively uniform particle sizes. The Ni-Mn-Zn ferrite have the maximum magnetic saturation strength and coercive force (84.97 A∙m2∙kg−1 and 7.44×10−3 T, respectively). It also shows the best microwave absorption properties. When the thickness of the Ni-Mn-Zn ferrite/paraffin composite was 8.62 mm and the frequency was 3.87 GHz, the minimum reflection loss RL,min was −41.77 dB. When the thickness was 8.09 mm, the maximum effective absorption bandwidth EAB,max was 3.1 GHz. The microwave absorption mechanism is mainly ascribed to the conduction loss due to polarization and the magnetic loss due to natural resonance and eddy current resonance. © 2023 Zhejiang University.
