Abstract :
We present the magnetic and microstructural properties of a semi-hard magnetic material Fe-Co-B-Cu produced by two rapid solidification processes: melt-extraction and melt-spinning. The as-quenched material (in the ribbon or fiber form) has coercive field H c in the range of 8-12 kA/m and remanence Br of 0.7 T. The semi-hard magnetic properties were obtained as a result of the combined effects of composition and special microstructures produced in the rapid solidification process
