FePSe

FePSe is an iron-phosphorus-selenium intermetallic compound that belongs to the class of transition metal chalcogenides and pnictides. This is primarily a research material under investigation for its potential electronic and magnetic properties, rather than an established industrial engineering material. Interest in FePSe stems from its position within material families explored for thermoelectric applications, magnetic devices, and solid-state electronics where the combination of iron with phosphorus and selenium creates unique electronic band structures.
