ErMnGe
metal· JVASP-152139· ErMnGe
ErMnGe is an intermetallic compound combining erbium, manganese, and germanium, belonging to the rare-earth transition metal germanide family. This is primarily a research material studied for its magnetic and electronic properties rather than a widely commercialized engineering alloy. The material shows promise in magnetocaloric and thermoelectric applications where rare-earth intermetallics are explored for energy conversion and magnetic refrigeration systems, though it remains in the experimental phase without established broad industrial use.
