EuPd
EuPd is a stable metallic alloy consisting of europium and palladium that is frequently studied for its structural properties.
About EuPd
EuPd is a metallic intermetallic compound composed of europium and palladium. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement within the broader family of platinum-group alloy catalysts.
This material is characterized by its significant structural versatility, evidenced by its presence across multiple independent crystallographic databases. Its metallic nature and stable composition make it a subject of interest for researchers investigating the fundamental electronic properties of rare-earth transition metal alloys.
Key Properties
Cross-validated computational properties for EuPd, 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 EuPd. 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.

How It Compares
Within the platinum-group alloy catalysts class.
Within the diverse landscape of platinum-group alloys, EuPd distinguishes itself through its specific stoichiometry and structural stability compared to siblings like BaPd or LaRh. While many members of this class are explored for their catalytic potential, EuPd serves as a critical reference point for understanding how lanthanide-palladium interactions influence the overall stability and electronic behavior of the alloy system.
