CeInNi
CeInNi is a stable metallic compound formed from cerium, indium, and nickel that is frequently documented in structural databases.
About CeInNi
CeInNi is a metallic intermetallic compound composed of cerium, indium, and nickel. As a thermodynamically stable phase located on the convex hull, it represents a robust structural configuration that has been documented across multiple materials databases.
Its metallic nature makes it a subject of interest for researchers investigating the electronic and magnetic interactions inherent in cerium-based ternary systems. The compound's stability suggests it can be reliably synthesized for experimental characterization in solid-state physics studies.
Key Properties
Cross-validated computational properties for CeInNi, 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.
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 CeInNi. 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.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.
