Abstract(in English) | At present, one of the interesting attentions of chemistry and physics is a development of organic ferromagnetic materials. Grigoryan et al. have reported phthalocyanine (Pc) doped with alkali metals exhibits ferromagnetism. The purpose of our study is to enhance the magnetization for the sample in order to establish it as the level of practical magnetic materials. We have found that FePc doped with potassium exhibits ferromagnetism. The magnetization increases with reaction temperature and time, then decreases with further reaction temperature and time, where the FePc molecule is partly decomposed. The magnetization observed as optimum was 15.3 emuG/g (a quarter of that of Ni) at 298K. The g-value of this sample in ESR measurements differs from that of free iron. It was observed the structure of the greater part of the sample was amorphous in XRD pattern. These results seem to indicate that the origin for the magnetism could not be supposed by free iron, but other magnetic interaction. |
