Process for producing organic ferromagnetic sustances. |
摘要 |
<p>An organic ferromagnetic substance including an amorphous carbonaceous substance in mid course of graphitization prepared from an organic compound having a hydrogen/carbon ratio of 1.7 or more and a process for producing same are disclosed. This organic ferromagnetic substance is stable and easy to produce, and has a high saturation magnetization and is advantageous as an industrial product such as a toner for copiers utilizing its light weight and high saturation magnetization.</p> |
