Summary:With the rapid development of precision guidance and radar detection technologies, radar absorbing materials have gained popularity. Traditional radar absorbing materials are limited because of a high density and narrow absorption band. To improve the absorption properties of traditional radar absorbing materials, developing radar absorbing material with thin-layer, light-weight, broadband and strong-absorbing is necessary. The effects of Co-doping on the structure, morphology, and microwave absorption properties of reduced graphene oxide (RGO)/Fe3O4 composites were studied in this paper. The RGO/Fe3O4 and Co-doped RGO/FeFe3O4 composites were prepared via a one-step hydrothermal method. The effects of Co on the microstructure, phase composition, and valence state of the composite were analyzed using scanning electron microscopy, X-ray diffractometry, and X-ray photoelectron spectroscopy. The relative complex permittivity and permeability of RGO/Fe3O4 and Co-doped RGO/Fe3O4 composites were within 2-18 GHz, as
