摘要： A manganese carbide (Mn4C) magnetic material and a production method therefor are provided. According to one embodiment, the saturation magnetization of the Mn4C magnetic material increases with increasing temperature, and thus the Mn4C magnetic material is applicable to fields in which thermally induced magnetization reduction is critical.
