Surface properties of the clean and Au/Pd covered Fe${}_3$O${}_4$(111): a DFT and DFT+$U$ study

Adam Kiejna, Tomasz Ossowski, Tomasz Pabisiak

The spin-density functional theory (DFT) and DFT+$U$ with Hubbard $U$ term accounting for on-site Coulomb interactions were applied to investigate structure, stability, and electro…
