6 Correlation Energies in Distorted 3 d - t 2 g Perovskite Oxides
Using an effective low-energy Hamiltonian derived from the first-principles electronic structure calculations for the narrow t2g bands of YTiO3, LaTiO3, YVO3, and LaVO3, we evaluate the contributions of the correlation energy (EC) to the stability of different magnetic structures, which can be realized in these distorted perovskite oxides. We consider two approximations for EC , which are based...
متن کاملGeneralized trends in the formation energies of perovskite oxides.
Generalized trends in the formation energies of several families of perovskite oxides (ABO3) and plausible explanations to their existence are provided in this study through a combination of DFT calculations, solid-state physics analyses and simple physical/chemical descriptors. The studied elements at the A site of perovskites comprise rare-earth, alkaline-earth and alkaline metals, whereas 3d...
متن کاملRedetermination of the distorted perovskite Nd0.53Sr0.47MnO3
Neodymium strontium manganese oxide with ideal composition Nd(0.5)Sr(0.5)MnO(3) was reported to have two different structure models. In one model, the x coordinate of an O atom is at x > 1/2, while in the other model the x-coordinate of this atom is at x < 1/2. Difference-density maps around this O atom obtained from the current redetermination clearly show that the structure with the O atom at...
متن کاملOrbital physics in the perovskite Ti oxides
Titanate compounds have been recognized as key materials for understanding the coupling of magnetism and orbitals in strongly correlated electron systems. In the perovskite Ti oxide RTiO3 (where R represents the trivalent rare-earth ions), which is a typical Mott–Hubbard insulator, the Ti t2g orbitals and spins in the 3d1 state couple each other through the strong electron correlations, resulti...
متن کاملPrediction of Formability in Perovskite-Type Oxides
Abstract: Prediction criterions for the formabilities of perovskite-type oxides are obtained by using the empirical structure map methods constructed by two parameters octahedral factor (rB/rO) and tolerance factor, on this structure map, simple point representing systems of forming and non forming are distributed in distinctively different regions. In this paper we found that the octahedral fa...
