Abstract
In this work, the Fe3O4 nanoparticles from natural iron sand were doped with Mn and combined with reduced-graphene oxide (rGO) to obtain MnxFe3–xO4/rGO nanocomposites with mole fraction variations of the Mn of 0.25, 0.5, and 0.75. The crystalline phase of the synthesized MnxFe3–xO4/rGO nanocomposites formed an amorphous phase. The presence of rGO was observed through EDX results. The magnetical properties of MnxFe3–xO4/rGO nanocomposites were shown by decreasing the Br, HcJ, Hmax along with increasing of Mn doping. Interestingly, increasing rGO and Mn composition made the absorption bandwidth of the MnxFe3–xO4/rGO nanocomposites wider, so that the radar absorption also increased marking by the greater reflection loss that reached −11.95 dB. The increase in the radar absorption performance of MnxFe3–xO4/rGO nanocomposites came from the efficient complementarity between dielectric loss and magnetic loss and interfacial polarization between Fe3O4 doped Mn and rGO.
