SAMARIUM-IRON-BISMUTH-NITROGEN-BASED MAGNET POWDER AND SAMARIUM-IRON-BISMUTH-NITROGEN-BASED SINTERED MAGNET

摘要

To provide magnet powder having high coercivity and a high decomposition temperature.SOLUTION: Samarium-iron-bismuth-nitrogen-based magnet powder includes a main phase including samarium, iron, and bismuth. In the samarium-iron-bismuth-nitrogen-based magnet powder, a ratio of bismuth with respect to a total amount of samarium, iron, and bismuth is less than or equal to 3.0 at%.SELECTED DRAWING: None
