About holmium titanate
Ho2Ti2O7 is a complex oxide that crystallizes in the pyrochlore structure. As a thermodynamically stable compound, it occupies a significant position on the convex hull, indicating robust structural integrity under standard conditions.
This material functions as a wide-gap insulator, a characteristic that makes it a primary subject for investigating exotic magnetic phenomena such as spin ice behavior. Its unique electronic and structural configuration allows researchers to probe fundamental physics at the intersection of geometry and magnetism.
Key Properties
Cross-validated computational properties for holmium titanate, aggregated across 3 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.
