Abstract: Magnetic nanoflakes fabricated by surfactant assisted, wet, high energy ball milling of bulk precursors, with or without preceding dry, high energy ball milling, wherein certain nanoflakes indicate hard magnetic properties, crystallographic texture and magnetic anisotropy.

Abstract: RE-TM based permanent magnets (single phase, hybrid, laminated or polymer bonded magnets) fabricated by using nanoflakes produced by surfactant assisted, wet, high energy ball-milling, with or without prior dry high energy ball-milling, where RE represents rare earth elements and TM represents transition metals.

Abstract: Composite RE-TM permanent magnets fabricated by using powders and nanoflakes produced by surfactant-assisted, wet, high energy, ball milling, with or without prior dry, high energy, ball milling; where RE represents rare earth elements and TM represents transition metals and where the powders include Fe nanoparticles, Fe—Co nanoparticles, B2O3, mica, MoS2, CaF2 powders and combinations thereof.

Abstract: Synthesis of iron nanoparticles with a substantially unoxidized iron core and a biocompatible coating is described. The nanoparticles are formed by reacting an iron salt solution with a reducing agent in a substantially oxygen-free environment and exposing the formed iron particles to a biocompatible coating agent in a substantially oxygen-free environment to form coated iron particles. An average diameter of the coated iron particles is between 5 nm and 25 nm. The biocompatible coating can functionalized with cell-specific agents for use as diagnostic and therapeutic agents.

Abstract: Dielectric rare earth fluorides are blended with rare earth magnet powders to produce high-resistivity fluoride composite rare earth magnets.

Abstract: A hard magnetic alloy free of rare earths, consisting of 14-20% of a transition metal (Zr or Hf), 1-5% silicon, 0.3-5.6% boron, and the remainder essentially cobalt, the alloy having a microstructure substantially devoid of nonmagnetic phases and consisting of a high proportion of (Co-Si).sub.11 TM.sub.2 phase and a lesser proportion of (Co-Si).sub.23 TM.sub.6 phase, such phases being distributed throughout in a regular manner in a fine grain. Substitution agents of nickel or iron may be used for up to 10% of the cobalt, substitutional agents of vanadium or niobium may be used for up to 5% of the TM, and aluminum, copper, or gallium for up to 2% of the silicon. The alloy has high coercivity, high temperture stability, and excellent corrosion resistance. The alloy may be processed directly by extrusion with reduced requirements for boron and silicon.
