· JVASP-12311· ErFe4Ge2

ErFe4Ge2 is an intermetallic compound combining erbium, iron, and germanium, belonging to the rare-earth iron germanide family of materials. This is a research-phase compound primarily investigated for its magnetic and thermal properties rather than a commercial engineering material. The material is studied in condensed matter physics and materials science contexts for potential applications in advanced magnetic devices, magnetocaloric systems, and low-temperature physics, where rare-earth intermetallics offer opportunities for tailored electronic and magnetic behavior unavailable in conventional alloys.
