Abstract

A magnetic material may include α″-Fe(NZ)or a mixture of α″-FeNand α″-FeZ, where Z includes at least one of C, B, or O, and x is a number greater than zero and less than one. In some examples, the magnetic material including α″-Fe(NZ)or a mixture of α″-FeNand α″-FeZmay include a relatively high magnetic saturation, such as greater than about 219 emu/gram, greater than about 242 emu/gram, or greater than about 250 emu/gram. In addition, in some examples, the magnetic material including α″-Fe(NZ)or a mixture of α″-FeNand α″-FeZmay include a relatively low coercivity. Techniques for forming the magnetic material are also described.
