In this paper, we report on the microwave absorbing properties of the Ni/SiO2 core/shell soft magnetic material which was synthesized by the tetraethyl orthosilicate (TEOS) hydrolysis method. The SEM patterns were shown that the particles of Ni/SiO2 were more dispersed and homogeneous. Microwave absorbing properties were measured in the range of 0.1–18 GHz. A reflection loss (RL) exceeding −20 dB in the frequency range of 2.6–8.9 GHz was achieved for an absorber thickness of 2.0–5.6 mm, and an optimal RL of −49.5 dB was obtained at 4.4 GHz for the thickness of 3.5 mm. The good microwave absorption properties resulted from a proper impedance match as a consequence of the insulator SiO2 around Ni particles.

We synthesized SiC nanorods/Ni core-shell structure (SiCR-Ni) by a facile solution method and researched their dielectric and microwave absorption properties. The dielectric and microwave absorbing properties of SiCR-Ni are superior to SiC nanorods (SiC[Formula: see text]. The maximum absorption peak of SiCR-Ni is almost three times that of SiCR. The bandwidth of effective absorption of SiCR-Ni covers 64% of [Formula: see text]-band. The improved properties of SiCR-Ni originate from multi-polarization in the special core-shell structure of SiCR-Ni.
