· JVASP-12378· HoMnGe

HoMnGe is an intermetallic compound combining holmium, manganese, and germanium, representing a rare-earth transition-metal germanide system. This material belongs to the family of Heusler-type or related intermetallic phases studied primarily in condensed-matter physics and materials research for magnetic and electronic properties rather than structural engineering applications. While not yet established in mainstream industrial production, compounds in this material family are investigated for potential applications in magnetic devices, thermoelectric energy conversion, and quantum materials research where the interplay between rare-earth magnetism and transition-metal electronic structure offers tunable functional properties.
