Structural and magnetic properties of nanocrystalline Fe–N thin films and their thermal stability

Structural stability and magnetism of γ′-Fe4N and CoFe3N compounds

“…So it has received much attention as a promising material for several applications, e.g., high density magnetic recording material, hard and wear-resistant materials [4][5][6]. ␥ -Fe 4 N belongs to the antiperovskite crystal structure, where the iron atoms occupy the two nonequivalent sites, namely, the corner (c) sites and face-centered (f) sites, while the nitrogen atoms sit at the body-centered (b) positions.…”

FMR study of samples obtained by nitriding and nitrides reduction of nanocrystalline iron

“…Nitriding reaction is of great industrial interest due to its influence on the surface hardness as well as wear and abrasive resistance of the nitrided surface [1][2][3][4][5][6][7][8][9][10]. Nitriding technology has been widely used also in improving material fatigue life, corrosion resistance and resistance of surface to softening effect.…”

Preparation and the influence of Co, Pt and Cr additions on the saturation magnetization of α″-Fe16N2 thin films

“…To resolve this long debated issue, many theoretical attempts [8][9][10] have also been made but no calculation based on band structure could successfully explain the mystery behind the giant magnetic moment in this phase of iron nitride. The contradiction might be due to the fact that ␣ -Fe 16 N 2 exists only as a meta-stable phase and thermally less stable [3] as compared to the other strong ferromagnetic phase of iron nitride [11][12][13]. Jack [14,15] suggested to improve the thermal stability employing both interstitial and substitutional alloying elements to develop ␣ -(Fe,X) 16 N 2 (X = metal) phases, with the aim of incorporating them into thin film heads for high-density disk drives.…”
