· JVASP-79141· MnNi2Ge

MnNi2Ge is an intermetallic compound belonging to the family of transition metal-based ternary alloys, combining manganese, nickel, and germanium in a defined stoichiometric ratio. This material is primarily investigated in research contexts for its potential magnetocaloric and magnetostructural properties, making it of interest for advanced functional applications rather than conventional structural engineering. The MnNi2Ge system and related variants are studied for refrigeration, sensing, and energy conversion applications where magnetically-driven phase transformations can be exploited.
