· Mn2 Co1 As1

Mn₂CoAs is a ternary intermetallic semiconductor compound combining manganese, cobalt, and arsenic elements in a defined stoichiometric ratio. This material belongs to the class of Heusler-type or half-metallic compounds, which are of significant interest in spintronics and magnetoelectronic applications due to their potential for 100% spin polarization at the Fermi level. While primarily a research-phase material rather than an established commercial product, Mn₂CoAs and related ternary arsenide systems are being investigated for next-generation spin-dependent electronic devices where controlling spin transport and exploiting magnetic properties are critical to device function.
