Ho4 Ni2 As4

Ho₄Ni₂As₄ is an intermetallic compound containing holmium, nickel, and arsenic, belonging to the family of rare-earth transition-metal arsenides. This is a research-phase material primarily studied for its electronic and magnetic properties rather than established industrial production. Interest in this compound centers on its potential applications in thermoelectric devices, magnetic materials research, and quantum phenomena exploration, where rare-earth intermetallics often exhibit unusual electronic structures and responses.
