Abstract
Electronic and elastic properties of recently discovered FeO2 were studied using ab initio band structure calculations within the generalized gradient approximation (GGA). This novel oxide can be one of the constituents of the Earth's lower mantle. We found that electronic structure of FeO2 practically does not change in the pressure range 76-290â¯GPa. The bulk modulus (B0) of FeO2 is 280â¯GPa and is of order of magnitude of B0 in perovskite (Mg, Fe) SiO3 and SiO2.
