α″-Fe 16 N 2 has been suggested as a promising candidate for future rare-earth-free magnets. In this paper, a unique technical route including a ball milling approach and shock compaction is experimentally demonstrated as a promising way to produce an α″-Fe 16 N 2 magnet. Firstly, α″-Fe 16 N 2 powder is prepared by ball milling, in which …
Since then, α″-Fe 16 N 2 has been picked up as one of the most promising rare-earth-free magnet candidates because of its use of environment-friendly raw materials, confirmed giant saturation magnetic flux density (2.9 T), and reasonably high magnetic anisotropy constant (1.8 MJ/m 3). Its coercivity temperature coefficient (~0.4 Oe/°C) in ...
