Preparation and coercive force of melt-spun Pr-Fe alloys

Abstract

Amorphous Pr1-x-Fex (0.45≤x≤0.90) alloys were prepared over a wide compositional range by melt spinning. Significant room-temperature intrinsic coercivities were found; a maximum of 2.8 kOe was found at composition x=0.6. At reduced temperature (20 K) coercivities as high as 60 kOe were observed. High-purity constituents were required to obtain amorphous samples over the composition interval 0.66≤x≤0.90.
