Structural and magnetic properties of NiCxand NiNx(x=0toFang1, Sluiter2, Huis3 et al. 2012Phys. Rev. B

“…This difference is useful to identify and distinguish the Ni phases and Ni 3 X phases in different forms, such as in nanocrystals or in thin films. [6][7][8][9][10][11][12]19,23,24 Both hcp-and 3R-Ni 3 X phases have hexagonal closepacked (hcp) Ni sublattices ( Fig. 1 and Table II).…”

“…[1][2][3][4][5][6][7][8][9][10][11][12] In recent years, much attention has been paid to different Ni 3 X materials, such as nanosized crystallites [3][4][5][6][7][8][9][10] and thin films. 11,12 Ni 3 N samples were first prepared by means of nitridation of Ni metal using ammonia.…”

Synthesis of Ni3N/SiO2 nanocomposites and investigation of their intrinsic static and dynamic magnetic properties

“…1,2 For example, some nitrides of transition metals and alloys can be used in corrosion resistant and optical coatings, electrical contacts, diffusion barriers, and magnetic data storage devices, while their corrosion resistance and magnetic properties such as magnetic moment and coercivity can be effectively manipulated by appropriate incorporation of nitrogen into the lattice. 12 In general, it is difficult to obtain pure samples with high homogeneity using those methods and the product is not pure-phase Ni 3 N but actually a mixture of different nitride phases with very different physical properties or contain residual Ni metal, which adds to the diversity of the reported physical properties of as-synthesized Ni 3 N. [13][14][15][16] Therefore, much remains to be claried. 5,6 As a typical class of metastable nitride, Ni 3 N has been known to be rather stable at room temperature and is a potential material in some applications in the recent literatures, 7 e.g., in lithium ion batteries 8,9 and in the eld of catalysis.…”

Gas-Phase Synthesis of Film Structures of Ni—N System

“…2, a, b and Table 2), which has been identified by us as Ni 2 N (b.c.t.). This phase is mentioned in references in very rare cases [5,12] and by now is studied insufficiently. Intensity of its reflexes increases at the further increase of nitrogen concentration in the growth atmosphere.…”
