Abstract

The magnetic properties of overquenched and annealed melt spun Fe79.6Nd13.2B6Si1.2 ribbon and of hot pressed magnets produced from this ribbon are reported. Remanence enhancement relative to the Stoner-Wohlfarth limit for randomly oriented grains, was observed. The highest remanence achieved was 0.87 T which is, however smaller than the values that we obtained by direct quenching (up to 0.95 T) and which were reported earlier. The difference is ascribed to a larger crystallite size (30-50 nm) in the annealed ribbon, compared with grains as small as 14 nm in the as-spun crystalline ribbon.
