＜正＞ Referring to magnetic material,one would associate it with the alloys and compounds ofthe ferrous elements and rare earths.In fact,strong magnetism has nothing to do with or-ganic compounds or the inorganic compounds without elements of 3d or 4f electrons.Wheth-er there exists organic ferromagnetism is therefore a problem nobody had been able to dem-onstrate until the end of 1960s.The research on organic ferromagnets is a challenge to thebasic problems of the ferromagnetism such as the origin of magnetic moments,the magneticintermolecular exchange interactions,so it is of academic significance.Moreover,from the
