Spin-polarized electronic band structures of the Fe4N–Co4N system

Deposition and spin polarization study of Fe4N thin films with (111) orientation

“…This result is similar to the M s of Fe 4 N thin films reported by several other experimental works. 10,11,15 It is also consistent with our previous experiment result of Fe 4 N. 19 The M s of Fe 4 N obtained in this work shows smaller value than the theoretical calculation results that are in a range of 2.1-2.45 µ B /Fe atom [20][21][22] (1410-1650 emu/cm 3 ) at zero temperature (0K). We attribute the smaller M s of Fe 4 N thin films in our experiment to the thermal excitation on magnetization as well as the defects and grain boundaries of the thin film sample.…”

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

“…That suggests that this material has potential application as spin-carrier materials for spintronics devices. 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.…”

“…First, M 4 N nitrides with M ¼ Fe, Co and Ni, have unique electronic and magnetic properties and consequently have potential applications as magnetic recording materials, [1][2][3][4][5] as spin carriers in spintronics [3][4][5][6] and even as catalysts used for photocatalytic water splitting. 7 Second, there are two possible phases for M 4 N (the I-phase and the II-phase) that are structurally difficult to distinguish but that can have very different physical properties.…”

Exchange interactions and Curie temperatures of the tetrametal nitrides Cr4N, Mn4N, Fe4N, Co4N, and Ni4N

“…Many articles discussing the magnetic ground states, possible metamagnetic transitions under pressure, as well as densities of states of the tetrametal nitrides with perovskite structure are found in the literature [19,20,21,22,23,24,25,26,27,28,29]. It is the aim of the present article to create an understanding for the experimentally observed Curie temperatures of the magnetic tetrametal nitrides, to predict the Curie temperatures for compounds for which a direct measurement is inaccessible, and to serve as a reference for the expected intrinsic properties of these compounds.…”
