Document Type and Number:
WIPO Patent Application WO/2020/241380
Kind Code:
A1
Abstract:
This invention achieves a novel samarium-iron-nitrogen-based magnetic material that displays a higher coercive force. This samarium-iron-nitrogen-based magnetic material contains Sm, Fe, and N. The samarium-iron-nitrogen-based magnetic material further contains Ti, and further contains 2.5 atom% or less of Co, or does not contain Co. For instance, without being limited hereto, the Sm content may be 7 to 10 atom%, the Fe content may be 65 to 80 atom%, the N content may be 13 to 16 atom%, and the Ti content may be 0.5 to 1.5 atom%.
