MnNiSb is a ternary intermetallic compound composed of manganese, nickel, and antimony, belonging to the class of Heusler alloys and half-metallic ferromagnets. This material is primarily studied for spintronic and magnetoelectronic applications where its predicted half-metallic character (100% spin polarization) offers theoretical advantages in spin-valve devices, magnetic tunnel junctions, and magnetoresistive sensors. Engineers select MnNiSb-based compositions for next-generation magnetic memory and sensing devices where high spin polarization and tunable magnetic properties are critical, though it remains largely in research and early development phases rather than mature industrial production.
