Final Magnetic Moment0.001 μBCalculated total magnetic moment for the unit cell within the magnetic ordering provided (see below). Typically accurate to the second digit. |
Magnetic OrderingNM |
Formation Energy / Atom-3.217 eVCalculated formation energy from the elements normalized to per atom in the unit cell. |
Energy Above Hull / Atom0.000 eVThe energy of decomposition of this material into the set of most stable materials at this chemical composition, in eV/atom. Stability is tested against all potential chemical combinations that result in the material's composition. For example, a Co2O3 structure would be tested for decomposition against other Co2O3 structures, against Co and O2 mixtures, and against CoO and O2 mixtures. |
Density3.62 g/cm3The calculated bulk crystalline density, typically underestimated due calculated cell volumes overestimated on average by 3% (+/- 6%) |
Decomposes ToStable |
Band Gap4.284 eVIn general, band gaps computed with common exchange-correlation functionals such as the LDA and GGA are severely underestimated. Typically the disagreement is reported to be ~50% in the literature. Some internal testing by the Materials Project supports these statements; typically, we find that band gaps are underestimated by ~40%. We additionally find that several known insulators are predicted to be metallic. |

Displaying lattice parameters for primitive cell; note that calculated cell volumes are typically overestimated on average by 3% (+/- 6%). Note the primitive cell may appear less symmetric than the conventional cell representation (see "Structure Type" selector below the 3d structure)
