The magnetic properties of (Nd,Dy)-(Fe,Co)-B-Nb and Nd-(Fe,Co)-B magnets made by the melt spinning method with grooved and ceramic coated roll

Summary form only given. In another presentation of the conference, the properties of a grooved and ceramic coated roll of (Nd/sub 0.9/Dy/sub 0.1/)/sub 9/(Fe/sub 0.9/Co/sub 0.1/)/sub 85.5/B/sub 5.5/ composition are reported. With this roll, excellent magnetic properties are expected at other compositions. In this presentation, we show the magnetic properties of other composition magnets melt-spun with the grooved and ceramic coated roll.
