MgNi
MgNi is a metallic intermetallic compound formed from magnesium and nickel that exhibits metastable structural characteristics.
About MgNi
MgNi is a metallic binary compound composed of magnesium and nickel. As a metastable phase, it represents a specific structural configuration within the magnesium-nickel alloy system, characterized by its conductive electronic nature and lack of a band gap.
This compound is of significant interest in materials science due to the diverse structural arrangements it can adopt. Its existence across multiple databases highlights its importance in understanding phase stability and the complex bonding behavior between alkaline earth metals and transition metals.
Key Properties
Cross-validated computational properties for MgNi, 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.
