摘要

Metal/ferrites nanocomposites Fe_xNi_(1-x)/Ni_yFe_(3-y)O_4 (0 < x, y < 1) were synthesized by the hydrothermal method in a rotating autoclave. The structure and magnetic properties of the composites have been investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM). The possible reaction mechanism was investigated in detail. For Fe_xNi_(1-x)/Ni_yFe_(3-y)O_4 nanocomposites, there are high special saturation magnetization Ms and relatively low coercive force He, which are 78.2emu/g and 78.3 Oe, respectively.
