· JVASP-15178· PrFeSi2

PrFeSi₂ is an intermetallic compound combining praseodymium, iron, and silicon in a C11b crystal structure, belonging to the rare-earth metal silicide family. This material is primarily of research interest for its potential in thermoelectric and magnetic applications, as rare-earth iron silicides exhibit favorable electronic properties and thermal behavior at elevated temperatures. The compound represents an experimental platform for developing advanced functional materials rather than an established engineering workhorse, with applications being investigated in specialized high-temperature energy conversion and electronic device contexts.
