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: The disclosure describes techniques for forming nanoparticles including Fe16N2 phase. In some examples, the nanoparticles may be formed by first forming nanoparticles including iron, nitrogen, and at least one of carbon or boron. The carbon or boron may be incorporated into the nanoparticles such that the iron, nitrogen, and at least one of carbon or boron are mixed. Alternatively, the at least one of carbon or boron may be coated on a surface of a nanoparticle including iron and nitrogen. The nano particle including iron, nitrogen, and at least one of carbon or boron then may be annealed to form at least one phase domain including at least one of Fe16N2, Fe16(NB)2, Fe16(NC)2, or Fe16(NCB)2.

Abstract: A multi-surface nanoparticle source includes a first end having an inlet configured to receive a flow of gas, a second end comprising an outlet through which nanoparticles exit the nanoparticle source, and two or more targets spaced apart and arranged about an axis extending from the first end to the second end. At least at least one of the targets is hollow, and the inlet is arranged to direct a flow of the gas through the hollow target, between at least two of the targets, or both. The gas impacts the targets, releasing atoms from the target and through the second end. The targets may be arranged lengthwise and concentrically about the axis. In some cases, a multi-surface nanoparticle source includes one or more magnets. Nanoparticles formed with a multi-surface nanoparticle deposition system may be homogeneous or have a core-shell structure.
