摘要

The invention slightly the crystallization heat of reaction, the nanocomposite material alloy (powder) for the (nano composite) magnet and a production method suitable for fine, while for preparing a magnetic powder having a homogeneous tissue with reproducibility is satisfactorily effective at the same time, whereby to provide. ; General dietary _{Fe 100-xy R x B y,} Fe 100-xyz R x B y Co z, Fe 100-xyu R x B y M u or _{Fe 100-xyz-u R x} B y Co z M u to show that the nano-composite (nano composite) material alloy for the magnet. R is Pr and is either one of Nd, or containing elements of both above 90 atom%, and the rest of the rare earth elements containing less than 10%, a kind or more elements more than 10% of the other lanthanides or Y, M is Al, Si , Ti, V, Cr, Mn, Ni, Cu, Ga, Zr, Nb, Mo, Hf, Ta, W, Pt, Pb, Au and is one kinds or more elements selected from the group consisting of Ag. The composition ratio x, y, z, and u are, 2≤x≤6, 16≤y≤20, 0.2≤z≤7, 0.01≤u≤7 satisfied and, besides, the Bragg reflection peak of the X-ray diffraction is junan containing normal (Z) in a position corresponding to the crystal plane distance of 0.179nm ± 0.005nm and the intensity of the Bragg reflection peak is halo (halo) less than 5% more than 200% of the maximum intensity of the pattern, and body simip the square of the strength of the Fe (110) Bragg peak scattering is less than 5% of the maximum intensity of the halo pattern. ; Nanocomposite magnets
