Mg3Mn
Mg3Mn is a metallic, metastable intermetallic compound formed from magnesium and manganese that is frequently observed in structural studies.
About Mg3Mn
Mg3Mn is a metallic intermetallic compound composed of magnesium and manganese. As a metallic phase, it exhibits characteristic electron delocalization typical of alloys in this chemical family, reflecting the interaction between the alkaline earth metal and the transition metal components. The compound is characterized as being above the thermodynamic hull, suggesting it is a metastable phase under standard conditions. Despite its instability, it has been the subject of extensive structural investigations, with numerous reported configurations across multiple materials databases.
Key Properties
Cross-validated computational properties for Mg3Mn, aggregated across 5 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
