A magnetic nanoparticle (22), a magnetic nanomaterial (30), assembly (30), and a method for synthesising a magnetic nanoparticle, relating to thermodynamically stable and air stable ferromagnetic nanoparticles of adjustable aspect ratio made upon decomposition of organometallic precursors in solution in the presence of a reaction gas and a mixture of organic ligands. The magnetic nanomaterial comprises magnetic nanoparticles of homogeneous size, shape, and magnetic orientation that comprises a magnetic core (24,34) ferromagnetic at room temperature and/or operating temperatures, and a nonmagnetic matrix (26,36) encapsulating the magnetic core. This magnetic nanomaterial could be used in high frequency integrated circuit applications, such as used in wireless portable electronic devices, to enhance magnetic field confinement and improve passive component performance at MHz and GHz frequency in a variety of passive and active devices, such as transformers, on-chip signal isolation, inductors, and the like. <IMAGE> |
