摘要： A soft magnetic material includes a plurality of composite magnetic particles (40) each including a metal magnetic particle (10) and an insulation coating (20) covering the surface of the metal magnetic particle (10), wherein the insulation coating (20) contains Si (silicon), and 80% or more of Si contained in the insulation coating constitutes a silsesquioxane skeleton. Therefore, it is possible to effectively decrease a hysteresis loss while suppressing an increase in eddy-current loss.

摘要： The invention relates to an inductive component (10) whose soft-magnetic core (11) consists of a powder composite. Said powder composite is produced by mixing a ferromagnetic amorphous or nanocrystalline alloy powder with a ferromagnetic dielectric powder and a thermoplastic or duroplastic polymer. Unlike conventional injection-molded or cast soft-magnetic cores, cores from a composite comprising a dielectric ferromagnetic powder allow for packing densities of substantially more than 55% by volume.

摘要： The metallurgical powder composition suspensions of the present invention include a magnetic powder having an outer oxide layer suspended in a carrier fluid. Magnetic powders include iron-based powders, such as for example, powders of iron pre-alloyed with other elements. Alloying materials include columbium, silicon, calcium, manganese, magnesium, carbon, boron, aluminum, titanium, molybdenum, chromium, copper, nickel, gold, vanadium, phosphorus, or combinations thereof. Carrier fluids include silicon-based fluids and/or oils, such as hydrocarbon oils. The outer oxide layer includes alloy materials that are reacted/complexed with oxygen. Magnetic powders exhibit low rates of oxidation over a broad temperature range. Articles incorporating metallurgical powder composition suspensions include dampeners having a chamber, a piston that reciprocates in the chamber, and a source of magnetism operatively connected to the chamber. The source of magnetism, when activated, produces a magnetic field that changes the apparent viscosity of the metallurgical powder composition suspension.
