Abstract
Dendritic Fe0.6Co0.4 alloy was synthesized by low temperature hydrothermal method under strong alkaline condition.
Morphology, composition, structure, magnetic property and microwave absorbing property of the Fe0.6Co0.4 alloy were
characterized by scanning electron microscopy (SEM), energy diffraction spectrum (EDS), X-ray diffraction (XRD), vibrating
sample magnetometer (VSM) and vector network analyzer, respectively. XRD pattern reveals that the alloy shows bcc
structure. The saturation magnetization, coercivity and residual magnetization is 212.39 emu/g, 56.0 Oe and 9.1 emu/g,
respectively. The microwave absorbing property demonstrates that the minimum RL of the Fe0.6Co0.4 alloy is -14.08 dB at 3.1
GHz with a thickness 6.5 mm..
