HIGHLY MAGNETIC MATERIAL AND MANUFACTURE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a highly magnetic material produced at low cost and having at least high magnetism and good temperature characteristics. SOLUTION: A high magnetic material having a coercive force of not less than 1 kOe is made from an alloy comprising one or more element T selected from the group of Fe, Co, Ni, one or more rare-earth element R, and an element B, and having an amorphous phase as a main phase by a melt quenthing method and then by heat-treating the alloy at a rising temperature of not less than 10 K/min.
