Abstract
A magnetic material may include α″-Fe16(NxZ1-x)2 or a mixture of α″-Fe16N2 and α″-Fe16Z2, 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″-Fe16(NxZ1-x)2 or a mixture of α″-Fe16N2 and α″-Fe16Z2 may 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″-Fe16(NxZ1-x)2 or a mixture of α″-Fe16N2 and α″-Fe16Z2 may include a relatively low coercivity. Techniques for forming the magnetic material are also described.
