· JVASP-80329· MnFe2Ge

MnFe2Ge is an intermetallic compound combining manganese, iron, and germanium, belonging to the family of transition metal germanides. This material is primarily of research and academic interest rather than established industrial production, investigated for its potential magnetic properties and phase stability characteristics relevant to functional materials applications. The negative Poisson's ratio indicated by its elastic properties suggests potential auxetic behavior, making it noteworthy for emerging applications requiring unconventional mechanical responses under stress.
