摘要：In this study, an extremely simple one-step ball milling has been applied to fabricate the flaky Fe3O4/Fe composites. The obtained samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM), and vector network analysis (VNA). It is acknowledged that the ball-milling process has huge influence on the morphology and electromagnetic absorption capability. Compared with the raw Fe3O4, the saturation magnetization of Fe3O4/Fe composites improved greatly. When the thickness is just 1.25 mm, the reflection loss values below -10 dB can be achieved from 13.8 to 18 GHz, with a maximum reflection loss of -25.9 at 16.1 GHz. Obviously, the Fe3O4/Fe composites can be used as magnetic microwave absorbers due to its simple synthesis for the mass production standards. Moreover, this study also gives new enlightenment to design other magnetism/magnetism composites that can be applied to Ku-band such as satellite communications. (C) 2017 Elsevier B.V.
