“…The structure of Fe 3 Mo 3 N consists of NMo 6 octahedra corner shared with the Fe atoms located at the sites between the octahedra. NPs of MMoN 2 (M = Fe, Co, Fe 0.8 Mo 0.2 , Fe 0.8 W 0.2 ) with WC-type layered structure were also synthesized by sol–gel methods. − FeMoN 2 was synthesized by ammonolysis of Fe 3 Mo 3 N at 300 °C for 6 h, whereas (Fe 0.8 Mo 0.2 )MoN 2 and (Fe 0.8 W 0.2 )WN 2 were prepared from Fe 2 (MoO 4 ) 3 and Fe 2 (WO 4 ) 3 under NH 3 (g) at 700 °C for 96 h, respectively. Similarly, FeWO 4 was treated with NH 3 (g) at 800 °C for 12 h to obtain the FeWN 2 NPs .…”

Magnetic nanoparticles (NPs) are prominent in various fields of scientific research and applications such as magnetic energy storage, magnetic fluids, biomedical fields, and catalysis. Metallic Fe NPs are difficult to protect from air oxidation, and iron oxide NPs suffer from reduced magnetization. Iron nitrides have the advantage of retaining high saturation magnetization (M S ); for example, α″-Fe 16 N 2 and γ′-Fe 4 N have average magnetic moments of 2.9 and 2 μ B /Fe, respectively, which are comparable to 2.2 μ B /Fe for α-Fe. The iron nitrides are ferromagnetic (FM) up to a maximum lattice dilution of 25% nitrogen for ε-Fe 3 N. Even though Fe−N NPs are extremely attractive as magnetic materials, the focus has been majorly on the bulk powders and thin films. This review provides a comprehensive overview of the crystal structures, nitriding kinetics, and synthesis methodologies of binary, doped, and ternary nanostructures, thin films, and bulk materials and their magnetism. Substitution of Fe by any other metal atom in the doped and ternary nanostructures breaks the long-range FM ordering but equally provides interesting low-temperature magnetic ordering such as spin glass and exchange bias. The dopant concentration dependence of the magnetic properties of the hybrid systems is discussed.

“…In recent years ternary nitrides containing two transition metals have raised a lot of interest, especially after FeWN 2 was reported in 1993. Most of the new compounds have been prepared by ammonolysis of ternary oxide precursors at temperatures between 600 and 800 °C: MWN 2 from MWO 4 (M = Mn, Fe, Co, Ni), − MnMoN 2 from MnMoO 4 , (Fe 0.8 W 0.2 )WN 2 from Fe 2 (WO 4 ) 3 , (Fe 0.8 Mo 0.2 )MoN 2 from Fe 2 (MoO 4 ) 3 , Fe 3 Mo 3 N from FeMoO 4 , and Ni 3 Mo 3 N from NiMoO 4 . A closer look at the ammonolysis reactions of MWO 4 (M = Fe, Co, Ni) to form MWN 2 nitrides revealed that it is probably a two-step reaction forming an intermediate phase at ∼420 °C .…”

The chemistry of ternary nitrides is reviewed with special focus on developments of the last two years (1996 and 1997). In particular, structures and properties of ternary and higher transition metal nitrides, main group nitrides, subnitrides, and nitride halides are compared, and a section on thermodynamics of ternary nitrides is included. Finally, methods for the preparation of gallium nitride single crystals are summarized.

“…Similar behavior is known from ternary inter-transition metal nitrides as, e.g., FeWN 2 and MnMoN 2 . [71][72][73] The temperature dependencies of the magnetic susceptibilities of the four known Sr and Ba phases can be interpreted as the sums of diamagnetic core contributions, weakly temperature dependent Pauli paramagnetic terms and minor Curie impurities. The resulting Pauli paramagnetic contribution indicates quite similar electronic densities of states at the Fermi level for all four phases (A 3 N)E with A = Sr, Ba; E = Sb, Bi of about 7.5 states per eV, in qualitative agreement with electronic band structure calculations (see below).…”
