· JVASP-106076· FeCoAs4

FeCoAs₄ is an iron-cobalt arsenide intermetallic compound belonging to the class of transition metal pnictides. This material is primarily of research interest rather than established in mainstream engineering applications, studied for its potential in thermoelectric devices, magnetic applications, and high-performance alloy development due to the favorable combination of iron and cobalt with arsenic bonding.
