Characterizations of soluble and insoluble products prepared from di-n-propylamine by CVD method were carried out using GC-MS and XPS methods in addition to magnetic measurements. GC-MS analysis of hexane-soluble product showed the presence of a series of aromatics with aromatic nitrile and/or heterocyclic compounds. XPS spectra of insoluble carbon product exhibited little difference in the Cls binding energy between plasma-treated and -untreated samples. However, it is found that the amorphous-like carbon content, calculated from the Cl_{s} energy loss spectra, is dependent on the plasma power and attains a maximum at 120 W, in good accordance with a plasma dependence of the apparent saturation magnetization of the carbons.(Fig.1)
