MnNiSb
metal· MnNiSb
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.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
