“…In agreement, electronic structure calculations reveal positive formation energies for the composition Fe 3 CoN. Disorder is easily rationalized by the alike chemical behavior of iron and cobalt together with very similar atomic radii, although indications for a minute preference of Co avoiding nitrogen in direct neighborhood for this composition was obtained in an independent study , . A fully ordered variant of Fe 3 CoN was predicted to exhibit a ferromagnetic ground state with a total magnetic moment similar to the value for γ′‐Fe 4 N , .…”

Research interest in inverse perovskite nitrides, since the early beginnings in the 1940s has considerably intensified in recent years. Within the last decades exploration lead to a wide variety of new compounds, compositions and structural arrangements. Electronic properties of the novel materials span from insulating and semiconducting via semimetallic and metallic, depending on element combination. Similarly, magnetic properties qualify for various applications, according to frequently high Curie temperatures and saturation magnetizations, together with development of delicate magnetic structures and often occurring metamagnetic transitions, to give only few examples. This minireview is intended to give an overview on formation of such metal‐rich compounds with focus on chemical systems and crystal chemistry.

“…In addition, the lattice constants of CNF thin films are larger than the previous theoretical result (a = 3.789 Å) [26] and experimental result (a = 3.790 Å) [17] about Fe 4 N, indicating the nearly stoichiometric of the derived CNF thin film. The calculation results reported previously show that the lattice constant of Fe 4 N decreases with the increase of nitrogen vacancies [27]. As mentioned above, copper doping facilitates the entry of nitrogen into the lattice, which can be interpreted by atomic electronegativity.…”

Synthesis and Physical Properties of Antiperovskite CuNFe3 Thin Films via Solution Processing for Room Temperature Soft-Magnets

Antiperovskite CuNFe3 (CNF) thin films have been successfully prepared by chemical solution deposition (CSD) for the first time. They are versatile in many applications as an iron-based nitride. The preparation of pure CNF thin films is a challenging work for the complexity of the phase diagram. Herein, the CNF thin films are phase-pure and polycrystalline. Annealing temperature effects on the microstructures and physical properties were investigated, showing that the CNF thin films are metallic and can be considered as a candidate for room temperature soft-magnets with a large saturated magnetization (Ms) and a low coercive field (Hc). At high temperatures, the electrical transport behavior of CNF thin films presents a low temperature coefficient of resistivity (TCR) value, while the electron–electron interaction is prominent at low temperatures. The reported solution methods of CNF thin films will enable extensive fundamental investigation of the microstructures and properties as well as provide an effective route to prepare other antiperovskite transition-metal nitride thin films.
