摘要： Provided are a magnetic powder having good high-frequency characteristics with low iron loss and good efficiency even at high frequencies, a method of producing a magnetic powder having good high-frequency characteristics with small degradation due to eddy currents and good absorption characteristics even at hyper-high frequencies, a magnetic material for magnetic field amplification having magnetic field amplification characteristics at high frequencies, and a magnetic material for hyper-high frequency absorption. Included is a method of producing a magnetic powder which includes performing a phosphorus treatment to obtain a phosphorus compound and a rare earth-iron-nitrogen-based magnetic powder, the phosphorus treatment including adding an inorganic acid to a slurry containing: a rare earth-iron-nitrogen-based magnetic powder containing R, Fe, and N, where R represents at least one selected from the group consisting of Y, Ce, Pr, Nd, Gd, Tb, Dy, Ho, Er, Tm, Lu, and Sm, and if R contains Sm, Sm constitutes less than 50 atm% of a total R content; water; and a phosphorus-containing substance. Also included are a magnetic material for magnetic field amplification and a magnetic material for hyper-high frequency absorption each of which contains a phosphorus compound and a rare earth-iron-nitrogen-based magnetic powder.

摘要： According to the present embodiment, there is provided a resin composition for bonded magnets which is excellent in physical properties such as heat resistance, bending strength, and IZOD impact strength without decreasing magnetic properties and which reduces generation of corrosive gas. There is provided: a resin composition for bonded magnets that includes a magnetic powder, a PPS resin, and a hydrotalcite powder, in which the content of the hydrotalcite powder is 0.1 to 25.0 wt% relative to the PPS resin; and a molded body of the resin composition for bonded magnets.
