· JVASP-15520· MnNi2Sb

MnNi₂Sb is an intermetallic compound belonging to the Heusler alloy family, characterized by a fixed stoichiometric ratio of manganese, nickel, and antimony atoms arranged in an ordered crystal structure. This material is primarily of research and development interest for spintronic and magnetic device applications, where it is studied for its potential half-metallic ferromagnetic properties that could enable high-efficiency spin-polarized electron transport. Its notable advantage over conventional magnetic alloys lies in the theoretical possibility of 100% spin polarization at the Fermi level, making it attractive for next-generation magnetoresistive sensors, spin valves, and magnetic memory devices, though practical device implementation remains largely in the research phase.
