N2 - The effective microwave absorption materials could contribute to alleviating the electromagnetic wave pollution. However, conventional microwave absorption materials usually suffer from insufficient absorption intensity and the narrow effective absorption bandwidth. Herein, BiFeO3/BaFe7(MnTi)2.5O19 composites are proposed to address these issues through offering synergetic electromagnetic properties and proper electromagnetic properties. BiFeO3 combined with BaFe7(MnTi)2.5O19 exhibits dielectric multiple relaxation behaviors, strong ferromagnetic resonance and electromagnetic matching, ensuring increased multi-band microwave absorption. Accordingly, the minimum reflection loss (RL) of the composite with volume ratio of 1.5:1 reaches − 48 dB, and the bandwidth less than − 10 dB covers multi-frequencies at C, X and Ku band. These results suggest that BiFeO3/BaFe7(MnTi)2.5O19 composite could be a promising microwave absorption material in imaging, healthcare, information safety and military fields.
