Abstract: The present invention relates to bulk magnetic nanocomposites and methods of making bulk magnetic nanocomposites.

Abstract: The present invention achieves a high-energy product using Ferromagnetic 3D elements such as nanowires and methods of making the same. The high energy products or magnets of the invention are able to achieve high magnetization and maintain the magnetic properties at a greater range of temperatures than currently known magnets. For example, a high energy product includes at least one material A selected from the group consisting essentially of Fe, Co, and Ni, wherein material A is in the form of nanowires formed by a solvothermal chemical process. A high energy product may also include at least one material A selected from the group consisting essentially of Fe, Co, and Ni, and at least one material B selected from the group consisting essentially of Fe, Co, and Ni, wherein material A and material B are in the form of an alloy of nanowires formed by a solvothermal chemical process.

Abstract: Provided herein are systems, methods, and compositions for magnetic nanoparticles and bulk nanocomposite magnets.

Abstract: The present invention provides an anisotropic bonded magnet and a method for fabricating the anisotropic bonded magnet by producing anisotropic chips by ball milling a rare-earth polycrystalline material with a surfactant in presence of a first magnetic field, mixing the anisotropic chips with one or more binding agents, and forming the anisotropic bonded magnet by compacting the mixture of anisotropic chips and binding agents in presence of a second magnetic field.

Abstract: The present invention includes particle compositions and methods of fabrication that prevent agglomeration, thereby maintaining particle size and/or shape. Particles of the present invention were prepared after embedding chemically disordered metal-containing particles in at least one salt to form a dispersion. The dispersion of particles in salt was treated to temperatures of at least about 500 degrees Centigrade for several hours. Particles were easily recovered from the dispersion and did not agglomerate. The particles were also absent contaminating salts after performing simple washing and/or rinsing steps. Structural, compositional and/or magnetic characterizations of the metal-containing particles confirmed that they had not agglomerated. When particles with an fcc structure formed a dispersion with at least one salt, the method yielded the formation of particles having an fct structure with high magnetic anisotropy and without a substantial change in size and/or shape.
