Abstract
Carbon-coated Fe particles have been produced by the Krätschmer- Huffmann carbon-arc discharge method. Soot, collarette and cathode samples have been separately characterised by Mössbauer spectroscopy and magnetisation measurements in the temperature range 4.2-300 K. From the analysis of the results the content of the different Fe phases and Fe-carbon solid solutions in our samples has been determined, as well as an estimation of particle sizes, which were found to be approximately 9 and 13 nm for the soot and collarette samples, respectively. © 2001 Elsevier Science B.V.
