Abstract

Abstract A novel synthetic material — ferromagnetic carbon (FMC) — produced in polyacrylonitrile pyrolitic decomposition has been studied via Auger electron spectroscopy (AES) and electron energy-loss spectroscopy (EELS). It has been stated, that the main impurities in FMC are nitrogen and oxygen; their content was measured to be 2.3 and 4.7 at%, respectively. In addition, the π- and (σ+π)-plasmon energies have been determined to be equal to 5.6 and 24 eV, respectively. A smaller number of π electrons in FMC than in graphite was found from analysis of the EEL spectra, in agreement with the theoretical model of FMC.
