PROBLEM TO BE SOLVED: To provide a Sm-Fe-N-based magnet exhibiting high coercive force.SOLUTION: A magnet represented by RFeTX, (R is one kind or more of rare earth element essentially containing Sm, T is one kind or more of transition metal element essentially containing Mo or Ta excepting Fe, X is one kind or more of N, C, B essentially containing N, where 6≤a≤14, 5≤b≤20, 8≤c≤18). The main phase particle contained in the magnet has a ThZntype structure, and a grain boundary phase where T is concentrated more than the main phase particle is contained in the grain boundary of the magnet.SELECTED DRAWING: None |
