A ternary composite of Ag/MnFe2O4/reduced graphene oxide (RGO) was synthesized by a facile hydrothermal method. The morphology, microstructure, magnetic and electromagnetic properties of as-prepared Ag/MnFe(2)O(4)RGO composite were characterized by means of XRD, TEM, XPS, VSM and vector network analyzer. The maximum reflection loss (RL) of Ag/ MnFe2O4/RGO composite shows maximum absorption of 38 dB at 6 GHz with the thickness of 3.5 mm, and the absorption bandwidth with the RL below 10 dB is up to 3.5 GHz (from 3.7 to 7.2 GHz). The result demonstrates that the introduction of Ag significantly leads to the multiple absorbing mechanisms. It is believed that such composite could serve as a powerful candidate for microwave absorber. (C) 2015 Elsevier B.V. All rights reserved.
