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.

Abstract: A permanent magnet may include a Fe16N2 phase constitution. In some examples, the permanent magnet may be formed by a technique that includes straining an iron wire or sheet comprising at least one iron crystal in a direction substantially parallel to a crystal axis of the iron crystal; nitridizing the iron wire or sheet to form a nitridized iron wire or sheet; annealing the nitridized iron wire or sheet to form a Fe16N2 phase constitution in at least a portion of the nitridized iron wire or sheet; and pressing the nitridized iron wires and sheets to form bulk permanent magnet.

Abstract: A magnetic device may include a layer stack. The layer stack may include a first ferromagnetic layer; a spacer layer on the first ferromagnetic layer; a second ferromagnetic layer on the spacer layer; and a dielectric barrier layer on the second ferromagnetic layer. In some examples, the layer stack may also include an additional ferromagnetic layer and an additional spacer layer. The magnetic device also may include a voltage source configured to apply a bias voltage across the layer stack to cause switching of a magnetic orientation of the second ferromagnetic layer without application of an external magnetic field.
