Fe2Gd

Fe2Gd is an intermetallic compound composed of iron and gadolinium, belonging to the rare-earth iron intermetallic family. This material is primarily of research and specialized interest rather than widespread industrial use, with applications emerging in magnetic materials and high-temperature structural alloys where the combination of iron's abundance and gadolinium's magnetic properties offers potential advantages. Engineers consider Fe2Gd compounds when designing systems requiring magnetic functionality, thermal stability, or specific electronic properties at elevated temperatures, though commercial availability and cost typically limit adoption to niche aerospace, energy, or advanced materials research contexts.
