The microstructure and magnetic properties of Mn–Sn–N and Mn–Sn–Co–N alloys were investigated. All the samples showed low remanences, although high coercivity of 876 kA/m was observed in the Mn–Sn–Co–N alloys. The substitution of Co for Mn increased coercivity. The sample with high coercivity consisted of a fine two-phase microstructure of 0.5–2 µm in size.
