Herein, the synthesis, structure, thermal stability, and magnetic properties of Ni 4 N thin films are studied. is difficult to synthesize in correct chemical order stoichiometry due unfavorable thermodynamics. During synthesis Ni–N films, it found that substrate temperature ( T s ) a critical parameter affecting growth phase. The phase transforms into an amalgamation [Ni+Ni 3 N] phases even if rises just above 300 K. These results elucidate correlation between atomic diffusion . self‐diffusion measurements carried out using secondary‐ion mass spectroscopy indicate substantial occurring at low A comparison coefficients Fe–N, Co–N, indicates lies Fe–N Co–N exhibits greater with enthalpy formation. transformation from cubic–to‐tetragonal deformation crystal lattice as function increasing concentration evident X‐ray diffraction absorption near‐edge measurements.
