摘　　要：碳原子线的制备是从马铃薯淀粉为固态碳源以Fe(NO3)3为催化剂前驱体,高温裂解制得。它的磁滞回线呈"S"形,一般只有铁磁性物质的磁滞回线才表现出"S",但一般铁磁性物质在常温下的饱和磁矩很大,大约为300 emu/g是碳原子线的300倍,我们把碳原子线的这种磁学性质称之为类铁磁性。通过碳原子线的顺磁共振谱图计算得到每个碳原子有4.78个自由电子,说明碳原子线中有大量的未成对电子。The carbon atom wires are prepared by pyrolysis of potato starch with Fe（NO3）3 as the catalyst precursor.The hysteresis loops showed ＂S＂ shape,generally only the hysteresis loop of the ferromagnetic materials showing ＂S＂.Saturation magnetic moment of common ferromagnetic materials is 300 times more than that of the carbon atom wire,about 300 emu/g under the room temperature,So we call this magnetic properties of the carbon atom wires as similar ferromagnetic property.Each carbon atom has 4.78 free electrons calculated by the paramagnetic resonance spectra of the carbon atom wires,which shows that the carbon atom wires have many unpaired electrons.
