<p>A sintered product which has a chemical composition, in wt %: R: 25 to 35 %, wherein R represents one or more of rare earth elements including Y, B: 0.5 to 4.5 wt %, one or two of Al and Cu: 0.02 to 0.6 %, Zr: 0.03 to 0.25 %, Co: more than 0 % and not more than 4 %, and the balance: substantially Fe, and has a coefficient of variation (CV value) representing the degree of dispersion of Zr of 130 or less. The sintered product allows the suppression of the growth of grains in combination of the minimization of the lowering of magnetic characteristics, and also allows the improvement of the width of sintering temperature.</p> |
