Magnetic properties and thermal modification of nanostructured films of nickel nitrides

Epitaxial growth and magnetic properties of NixFe4-xN (x = 0, 1, 3, and 4) films on SrTiO3(001) substrates

“…29 For these reasons, the T c of Ni 3 FeN has not been determined yet. In addition, we have only limited information about the magnetic properties of Ni 4 N. [30][31][32][33] In this article, we fabricated 20-60 nm-thick Ni x Fe 4-x N epitaxial films in a wide range of 0 x 4 and examined their (1)…”

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.…”

Predicted stability, structures, and magnetism of 3d transition metal nitrides: the M4N phases

“…The (in-)stability of paramagnetic I-M 4 N phases was investigated using the Stoner theory. [10][11][12]50,51 The obtained information here is important not only for solid state scientists to understand the nature of 3d transition metals and related compounds, but also for experimentalists for obtaining a reliable characterization of prepared samples and to understand the physical properties of the binary M 4 …”

“…6,[36][37][38][39][40] In the rst-principles' study of stability and electronic and magnetic properties of nickel nitrides, Fang and co-workers revealed that I-Ni 4 N is magnetic while I-Ni 4 N 1AEx (x $ 0.1) phases are non-magnetic due to the distortion of the FCC Ni sub-lattice caused by extra/deciency of N atoms. 41 More theoretical studies were conducted on the electronic and magnetic properties of ternary I-(A x M 1Àx ) 4 N phases where A is a metallic element and M a 3d transition metal.…”
