• Fe-Co alloys of 2–4.5μm diameters with microclusters morphology were synthesized using a facile hydrothermally method. The morphology and size of final products strongly depend on the reaction time and temperature. The microstructures and component of as-prepared samples were investigated in detail by X-ray powder diffraction (XRD), energy dispersive spectrometer (EDS), and scanning electron microscopy (SEM) techniques. The formation mechanism of such novel Fe-Co alloy was discussed on the basis of controlled experiments. The magnetic properties were characterized by vibrating sample magnetometer (VSM). The higher saturation magnetization of 197emu/g with low coercivity of 117.5Oe was obtained. Results from this study therefore suggest that Fe-Co microclusters could be applied in magnetic devices and other related fields.
