· JVASP-15295· TmMn2Ge2

TmMn2Ge2 is an intermetallic compound combining thulium, manganese, and germanium, belonging to the rare-earth transition metal family of materials. This is a research-phase compound studied primarily for its magnetic and thermal properties rather than established industrial production. Materials in this chemical family are investigated for potential applications in magnetocaloric cooling devices, high-temperature structural alloys, and advanced functional materials where rare-earth elements provide magnetic ordering and improved mechanical performance at elevated temperatures.
