Fe16N2 nanopowder composed of the α″-Fe16N2 phase exhibited a high saturation magnetization of 168 emu/g and a relatively high coercivity of 2.65 kOe under magnetic measurements with a DC magnetic field of 25 kOe at room temperature. A thermal study revealed that the α″-Fe16N2 phase in the Fe16N2 nanopowder was thermally stable up to 539 K. Fe16N2 nanopowder is, therefore, a prospective candidate for rare-earth-free magnets.

The high cost of rare earth materials, unstable supply and high demand remain big problems to solve for permanent magnet industries. Thus α″-Fe16N2 has been picked up as one of the most promising rare earth-free magnet candidates because of its use of environmental-friendly raw materials, confirmed giant saturation magnetic flux density (2.9 T), and reasonably high magnetic anisotropy constant (1.8 MJ/m3). Also, α”-Fe16N2 metastable with film form exhibits high tetragonality (c/a=1.1) by interstitial introduction of N atoms, leading to a high magnetocrystalline anisotropy constant (Ku = 1.0 MJ/m3). but synthesis of bulk form has lower properties than thin film (<230 nm) because of magnetic interaction, experimentally low anisotropy, and low density. In this paper, we review the synthetic methods of metastable α”-Fe16N2 with powder and bulk form and discuss the approaches to enhance magnetocrystalline anisotropy of α”-Fe16N2.
