Iron nitride thin films with high coercivity and good corrosion resistance

X-ray diffraction and Mössbauer study of (Fe1−xNix)4N (0.2≤x≤0.6) films

“…The corner Fe atoms (Fe c ) are surrounded by 12 nearest neighbors and the face-center ones (Fe f ) have two N atoms as nearest neighbors. This simple crystallographic structure makes it attractive for fundamental investigation, both theoretical [4] and experimental [5,6]. In order to improve the magnetic properties and the chemical stability of ␥ -Fe 4 N, one has synthesized and studied (Fe,M) 4 N by the substitution of a second transition metal M (M = Ni, Sn, Cu,.…”

Preparation and chemical stability of iron-nitride-coated iron microparticles

“…These properties of iron nitrides are useful in many fields. Thin iron films with nitrided surfaces [13][14][15] have been prepared to obtain a magnetic recording medium with strong resistance to oxidation and corrosion. Pure iron plate has been nitrided on the surface to achieve hardness and wear resistance [16].…”

Mössbauer study of (Fe1−xCux)4N (0.05⩽x⩽0.15) films

“…Among them, the nitride g 0 -Fe 4 N has been the object of intensive experimental and theoretical studies [1][2][3]. The interest in this nitride arises from the large saturation magnetization and good chemical stability.…”
