· Er2 Ni8 As4

Er2Ni8As4 is an intermetallic compound combining erbium, nickel, and arsenic in a defined stoichiometric ratio, belonging to the rare-earth transition-metal arsenide family. This material is primarily of research and academic interest rather than established industrial production, with potential applications in thermoelectric devices and magnetic systems that exploit rare-earth–transition-metal coupling effects. The compound's relevance lies in its potential for high-temperature applications and specialized electronic or magnetic functionality where rare-earth contributions are valuable.
