<P>PROBLEM TO BE SOLVED: To solve the problem, wherein a magnetic material that uses a transition metal, whose magnetism is developed by a d-orbit electron and imparts a large load to the environment, when it is discard. <P>SOLUTION: Excess carbon atom 2 is supplied among each single-layer graphite 3a in an ion implantation method, and the like; and when the distance between each single-layer graphite is compressed at heating, the supplied surplus carbon atom 2 is subjected to chemical bonding with a carbon atom 1, which constitutes the single layer graphite 3a on upper and lower sides. The number of chemical bonds of the inserted carbon atom 2 becomes 2, and two electrons which do not contribute to bonding are subjected to spin polarization, and magnetism is manifested. <P>COPYRIGHT: (C)2009,JPO&INPIT |
