Patent ID: 7955442

Claim:
A method for producing a sintered magnet comprising R (R: one or more rare-earth elements), T (T: one or more transition metal elements essentially comprising Fe, or Fe and Co) and B (boron) as the main components, wherein: strip casting a starting alloy, the strip casted starting alloy comprises a discolored deposit on a surface, decreasing the area ratio of said discolored deposit to 1.5% or less, by mechanically removing or screening out the discolored deposit from the strip casted starting alloy, pulverizing the strip casted starting alloy with the area ratio of said discolored deposit being 1.5% or less, by a jet mill in a non-oxidative atmosphere containing oxygen at 100 ppm or less to a given particle size to form a fine powder, wherein said fine powder is compacted in a magnetic field to prepare a compact, and said compact is sintered, and wherein R is contained in said sintered magnet in a range from 27.0 to 30.0% by weight of R.
