Abstract:
     Ferromagnetic powder consists of magnetic metal oxide powder and a layer of magnetic metals formed on the surface of the powder. At least one metal in the layer of magnetic metals selected from Fe, Co or Ni. The direction of magnetizing axis of the magnetizing action of the ferromagnetic powder is basically the same as that of original magnetic powder grains, but both the coercive magnetic force and the saturation magnetization of the magnetic powder are improved.
