✦ Synopsis

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 nand (o+r)-plasmon energies have been determined to be equal to 5.6 and 24 eV, respectively. A smaller number of x electrons in FMC than in graphite was found from analysis of the EEL spectra, in agreement with the theoretical model of FMC.

The electron energy loss spectrum of C6c in the gas phase from 1 to 30 eV is presented. The spectrum is similar to spectra of the solid, with shifts in the mutually observed bands seen only for the previously identified plasmon features. These results confirm this identification as well as provide a
