Abstract

See full text

An Sm—Fe—N-based magnetic material according to the present disclosure includes a main phase having a predetermined crystal structure. The main phase has a composition represented by a molar ratio formula (Sm(1-x-y-z)LaxCeyR1z)2(Fe(1-p-q-s)CopNiqMs)17Nh (where, R1 is a predetermined rare earth element, M is a predetermined element, and 0≤x+y<0.04, 0≤z≤0.10, 03 to 0.840 nm3, and a density of the main phase is 7.70 g/cm3 to 8.00 g/cm3.
