Large scale synthesis and formation mechanism of highly magnetic and stable iron nitride (ε-Fe3N) nanoparticles

Abstract

ε-Fe₃N magnetic nanoparticles with an average size of 45 nm were synthesized by nitriding the zero valent iron nanoparticle precursors using ammonia gas as a reactive ambience. The technique reported in this study is found to be promising in producing highly stable ε-Fe₃N magnetic nanoparticles and can be extended to other forms of Fe-nitrides.
