First-principles calculations of hematite (α-Fe2O3) by self-consistent DFT+U+V
Autor: Nelson Naveas, Ruth Pulido, Carlo Marini, Jacobo Hernández-Montelongo, Miguel Manso Silván
Publikováno v: iScience, Vol 26, Iss 2, Pp 106033- (2023)
Summary: Owing to the confined Fe-3d orbitals and self-interaction error of exchange-correlation functionals, approximate DFT fails to describe iron oxides electronic structure and magnetic properties accurately. Hybrid DFT or DFT + U can solve these
