About Dysprosium
Dysprosium is a metallic rare-earth element that occupies a stable position on the convex hull. As a heavy lanthanide, it is characterized by its distinct electronic structure which contributes to its exceptional magnetic properties and high thermal stability in various environments.
This element is highly valued in modern industry for its ability to enhance the coercivity of high-performance magnets. Its structural versatility is evidenced by the numerous crystalline forms documented across multiple materials databases, reflecting its importance in both fundamental research and industrial applications.
Key Properties
Cross-validated computational properties for Dysprosium, 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.
