Abstract: An internal structure of a magnetic material is phase-separated into at least a first phase and a second phase. At least one of the first phase and the second phase includes a compound having a perovskite structure. The first phase and the second phase include Mn, Sn, and N. According to this, it is possible to obtain a magnetic material in which magnetic properties such as a coercive force are improved. In addition, in a case where a rare-earth element is not included in elements that constitute the magnetic material, it is possible to obtain a magnetic material having corrosion resistance.
