PURPOSE:To easily mold colloid-size ferromagnetic fine particles into a flexible complex shape by dispersing the particles in a cured material of a medium for the fine particles in an assembled state, each said fine particle being yielded by adsorbing molecules each having affinity for the medium and coating the particle with the molecules over the surface thereof. CONSTITUTION:Nitrided metal fine particles 2 having a surface active agent coated layer 1 for example are arranged in the direction of a magnetic field at a predetermined interval, elongated lengthily on a straight line like a string of beads, and the arrangement is adapted to form a triangular lattice across a cross section perpendicularly to the direction of the magnetic field and is fixed in a medium 3. In such an orinted texture, the nitrided metal fine particles 2 are aligned at a predetermined distance by entropic repulsive force of the surface-active agent coated layer 1, the distance being controlled by the kind and molecules of a surface active agent used. Hereby, the fine particles can easily and simply molded into a flexible and complex shape. |
