Abstract

We have produced by high energy ball milling a nanocrystalline material in powdered form. The starting material was amorphous melt spun Fe_64.5Co₁₈Si₁B₁₆C_0.5. From the results of a systematic study of the dependence of the saturation coercive force on the annealing time and temperature it was evidenced the possibility of achieving coercivities as low as 0.150±0.004 Oe and therefore comparable with those measured in the as-quenched highly magnetostrictive melt spun samples of similar composition
