Abstract :
Melt-spun ribbons of Nd-Pr-Fe-Co-B system alloys were prepared by the single roller rapid-quenching method, and the effects of composition and substrate surface velocity on the magnetic properties were studied. A maximum energy product of 164.0 kJ/m3 (20.6 MGOe) was obtained with (Nd0.5Pr0.5)11 Fe72 Co8B9 alloy ribbon prepared at a substrate surface velocity of 17.1 m/s. The reversible temperature coefficient (from 25 to 125°C) of the ribbon magnet of (Nd0.5Pr0.5)11 Fe72Co8 B9 was α(Jr)=0.076%/°C
