Perovskite‐like ABO3 oxides A = (Ca, Sr, Ba) and B = (Ti, Mn, Fe, Co, Ni) show a large variety of structures and physical properties. Among them is BaTiO3 (BTO), one of the most investigated and used perovskites. In a BTO film on Pt(111), the first

The incorporation of Fe impurities in hexagonal barium titanate is studied in the framework of density functional theory. Formation energies are calculated to find the most probable defect structure. The substitution of Fe at the two inequivalent Ti

We studied the magnetic phase diagram of the rare-earth manganites series ${\mathrm{Gd}}_{1\ensuremath{-}x}{\mathrm{Ca}}_{x}{\mathrm{MnO}}_{3}$ (GCMO) over the full concentration range based on density functional theory. GCMO has been shown to form s

Internal structural distortions are of great interest in the determination of electronic and magnetic properties of the strong correlated rare earth manganites. When combined with external structural modifications like uniaxial or biaxial strains, st

The theoretical treatment of complex oxide structures requires a combination of efficient methods to calculate structural, electronic, and magnetic properties, due to special challenges such as strong correlations and disorder. In terms of a multicod
