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.
