Abstract

Nanoparticles of iron doped vanadium nitride are synthesized by simultaneous thermal decomposition and nitridation of [V(1 − x)Fe x O(NH2O)2Gly]·H2O in NH3 atmosphere at 973 K for 4 h. Pure VN shows cubic NaCl structure with lattice parameter of a = 4.126 Å. Lattice parameter increases with Fe-doping. Magnetization increases with increase of Fe amount in VN. Coercivity values are in the range 30–80 Oe, which is relatively so small, compared to pure Fe. From Mössbauer study, it is inferred that single resonance line is due to the high diamagnetic contribution and doublet peaks are due to the paramagnetic contribution, which is assigned to the presence of ζ-Fe2N phase.
