LaMg
LaMg is a stable metallic compound formed from lanthanum and magnesium that is frequently studied for its structural properties.
About LaMg
LaMg is a metallic intermetallic compound composed of lanthanum and magnesium. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of these two elements, reflecting a favorable energetic state that persists across diverse synthesis conditions.
Its metallic nature and structural reliability make it a subject of significant interest in materials science. With numerous reported structures documented across various databases, it serves as a foundational example for understanding binary lanthanide-magnesium systems and their potential for specialized metallurgical applications.
Key Properties
Cross-validated computational properties for LaMg, aggregated across 6 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of LaMg. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
