BaYFe4O7
BaYFe4O7 is a metastable, semiconducting oxide belonging to the hexagonal ferrite class of materials.
About BaYFe4O7
BaYFe4O7 is a complex ferrite characterized by its semiconducting electronic behavior and metastable nature. It represents a sophisticated structural arrangement within the broader family of hexagonal ferrites, where the interplay of barium, yttrium, and iron cations dictates its unique physical properties.
This material is of significant interest in condensed matter research due to its structural complexity and the potential for tunable magnetic properties. Its metastable state makes it a subject of intense study for understanding phase stability and synthesis pathways in oxide materials.
Key Properties
Cross-validated computational properties for BaYFe4O7, 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.

How It Compares
Within the spinel and hexagonal ferrites class.
Unlike the common spinel ferrites such as MgFe2O4 or ZnFe2O4, which typically exhibit robust stability, BaYFe4O7 occupies a more specialized niche as a metastable hexagonal ferrite. While compounds like SrFeO3 or BaFeO3 focus on perovskite-related frameworks, BaYFe4O7 utilizes its distinct cation coordination to achieve a different structural geometry, setting it apart from the more conventional cubic spinel members.
