AbstractZnFe2O4/graphite composites were synthesized by a high temperature ball milling method. Magnetic properties, electromagnetic response, and microwave absorption properties of the ZnFe2O4/graphite composites with different graphite were investigated by a vibrating sample magnetometer and a vector network analyzer in the 2-18 GHz frequency range. The minimum reflection loss of ZnFe2O4 reached - 19.72 dB at 13.04 GHz at the absorbent layer thickness of 2 mm, and the effective absorption bandwidth (RL < -10 dB) is 3.52 GHz covering a frequency range from 11.44 to 14.96 GHz. The composite with 10 wt% graphite (ZFO/ C10) showed excellent electromagnetic impedance matching performance. The minimum reflection loss of ZFO/C10 composite reached - 29.85 dB at 17.52 GHz at the absorbent layer thickness of 1.3 mm, and the effective absorption bandwidth (RL < -10 dB) reached 4 GHz covering a frequency range from 13.12 to 17.12 GHz at a thin thickness of 1.5 mm. Compared to the ZnFe2O4, the ZnFe2O4/graphite composites exhibited better microwave absorbing performance and wider effective absorption bandwidth. A possible microwave absorption mechanism for the ZnFe2O4/graphite composites was proposed. (C) 2022 Elsevier B.V. All rights reserved.
