Title: Nanoscale Metastable ε-Fe 3 N Ferromagnetic Materials by Self-Sustained Reactions

Abstract

A single-step method for the preparation of metastable ε-Fe 3N nanoparticles by combustion of reactive gels containing iron nitrate (Fe(NO 3) 3) and hexamethylenetetramine (C 6H 12N 4) in an inert atmosphere is reported. The results of Fourier transform infrared spectroscopy (FTIR) and thermal analysis coupled with dynamic mass spectrometry revealed that the exothermic decomposition of a coordination complex formed between Fe(NO 3) 3 and HMTA is responsible for the formation of ε-Fe 3N nanoscale particles with sizes of 5-15 nm. The magnetic properties between 5 and 350 K are characterized using a superconducting quantum interference device (SQUID) magnetometer, revealing a ferromagnetic behavior with a low-temperature magnetic moment of 1.09 μB/Fe, high room temperature saturation magnetization (~80 emu/g), and low remanent magnetization (~15 emu/g). The obtained value for the Curie temperature of ~522 K is close to that (~575 K) for bulk ε-Fe 3N reported in the literature.
