ABSTRACT Pr(Fe 0.6 Co 0.4 ) 2 ribbons were prepared by melt spinning with different wheel speeds from 35 to 45 m/s. Their structure, magnetic properties, and thermal stability are investigated. At a wheel speed of 35 m/s, the ribbon consists of a mixture of Pr(Fe,Co) 2 cubic Laves phase and some noncubic phases. An almost Pr(Fe,Co) 2 nanocrystalline single phase with a Curie temperature of 305 °C is obtained at a wheel speed of 40 m/s. Except for Pr(FeCo) 2 phase a small amount of amorphous phase is observed with increasing wheel speeds to 45 m/s. Pr(Fe,Co) 2 phase becomes unstable and decomposes above 770 °C. The resin-bonded Pr(Fe,Co) 2 nanocrystalline phase which is obtained at a wheel speed of 40 m/s combines high magnetostriction (λ||-λ⊥=140 ppm), with significant coercivity, iHc=5 kOe. © 2000 American Institute of Physics.
