PURPOSE:To provide a magnetic substance which is light in weight and excellent in workability and the manufacturing method of the substance. CONSTITUTION:A cation radical is produced by extracting one piece of pi electron from each carbon ball in which 60, 70, or 84 pieces of carbon atoms are coupled in a spherical state by dispersing and oxidizing the carbon balls in concentrated sulfuric acid. When the pi electron is extracted by one piece in such way, unpaired electron spins are added to the carbon balls and the balls are magnetized. The magnetized carbon balls show a ferromagnetic property. |
