| Abstract: | Several micro meter long nanowires of ε-FexN (2 < x < 3) are synthesized through a reduction nitridation method of Fe-NTA precursor formed by a hydrothermal method. The formation of pure iron nitride nanowires is confirmed by XRD. SEM analysis shows the porous nature of the iron nitride nanowires, which will enhance its suitability in catalysis. The field dependent magnetic behavior shows the ferromagnetic nature of the iron nitride nanowires. An appreciably good magnetization value (71 emu/g) and low coercivity (24 Oe) of the system makes it suitable for magnetic recording head applications. The room temperature Mössbauer study of the pristine nitride nanowires shows the existence of two iron sites corresponding to Fe (II) and Fe (III) indicating structural disorder. |
