Abstract
Iron plates were oxidised in a conventional r.f.-plasma using a mixture of methane and water vapour. Conversion electron Mossbauer spectroscopy and Ra man spectrometry were used to demonstrate that a complete transformation of iron surfaces into pure (single phase) magnetite (Fe3O4) was achieved. The thickness of the oxidised surface layer is similar to 200 nm. About 8% of the Fe-sites (B-sites) octahedrally coordinated by oxygen are vacant. (C) 1 999 Elsevier Science S.A. All rights reserved.
