Abstract

Large quantities of Fe1–xS (x = 0.12 and 0.1–0.08) nanowires (see Figure) have been prepared by the thermal decomposition of a hybrid precursor, Fe1–xS(en)0.5 (x = 0.2–0.3, en = ethylenediamine). Removal of the amine from Fe1–xS(en)0.5 at 200 and 300 °C under Ar flow yields Fe7S8 and Fe1–xS (x ≈ 0.09) nanowires, respectively, with well-defined morphologies. The Fe7S8 nanowires are ferrimagnetic at room temperature.
