The study of materials with lightweight and high-performance microwave absorption in low frequency range is of great significance for many critical fields. Nevertheless, the prominent issues of traditional absorbing materials such as high dielectric constant and thick thickness seriously restrict their practical applications. Consequently, ultimate aims for the development of high-performance multicomponent microwave absorbing materials with lightweight and high reflection loss are urgently required in the low frequency range. A spherical-like nanohybrids of reduced graphene oxide/ZnFe2O4/Ni (RGO/ZnFe2O4/Ni) in paraffin with an outstanding microwave absorption property was synthesized by hydrothermal method. When increased content of RGO/ZnFe2O4/Ni nanohybrids to 40 wt%, the best reflection loss (RL) of - 22.57 dB occurred at 4.21 GHz with a thickness of only 2.5 mm and the absorption bandwidth (RL
