PURPOSE: A manufacturing method of a nano complex magnet is provided to manufacture a nano-sized hard or a nano-sized soft magnetic composite magnet powder and a bond magnet or a sintered magnet by using a non-electrolytic deposition method. CONSTITUTION: A manufacturing method of a nano complex magnet using a non-electrolytic or an electrolytic deposition method is as follows. The surfaces of the activated nano particles are coated by dipping the surfaces of the activated nano particles into a plating solution which includes at least one metal ion selected from a group composed of nickel, iron, cobalt, aluminum, gold, platinum, silver, copper, palladium, tin, zinc, and chrome. The activation step is performed by a sensitization process which makes tin ions to be absorbed into the surfaces of ferrite nano particles and an activation process which forms a palladium activation layer on the surfaces of the ferrite nano particles. |
