Key Properties
Cross-validated computational properties for Sr4FeMoO8, aggregated across 2 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.

How It Compares
Within the spinel and hexagonal ferrites class.
Within the broad class of ferrites, Sr4FeMoO8 occupies a distinct niche compared to more common spinel-structured members like MgFe2O4 or ZnFe2O4. While it shares the fundamental ferrite building blocks, its stoichiometry and electronic character differentiate it from perovskite-related siblings such as Sr2FeMoO6 or SrFeO3. Unlike the simpler spinels, this compound offers a unique structural complexity that provides a different pathway for tuning electronic properties in oxide-based devices.
