Spin-orbital order in LaMnO $_{3}$ : $d - p$ model study

Krzysztof Rościszewski, Andrzej M. Oleś

Using the multiband $d - p$ model and unrestricted Hartree-Fock approximation we investigate the electronic structure and spin-orbital order in three-dimensional MnO $_{3}$ lattice such…

$d - p$ model and spin-orbital order in the vanadium perovskites

Krzysztof Rościszewski, Andrzej M. Oleś

Using the multi-band $d - p$ model and unrestricted Hartree-Fock approximation we investigate the electronic structure and spin-orbital order in three-dimensional VO $_{3}$ lattice. The…

On the Neglect of Local Coulomb Interaction on Oxygens in Perovskites Described by the Multi-band $d - p$ Model

K. Rościszewski, A. M. Oleś

On the example of TiO $_{4}$ layer (such as realized in Sr $_{2}$ TiO $_{4}$ ) we study electronic structure of multi-band $d - p$ models describing transition metal perovskites. In agreement w…

Multiband $d - p$ model and self-doping in the electronic structure of Ba $_{2}$ IrO $_{4}$

Krzysztof Rościszewski, Andrzej M. Oleś

We introduce and investigate the multiband $d - p$ model describing a IrO $_{4}$ layer (such as realized in Ba $_{2}$ IrO $_{4}$ ) where all $34$ orbitals per unit cell are partly occupied, i.e…

Charge transfer model for the electronic structure of layered ruthenates

Krzysztof Rościszewski, Andrzej M. Oleś

Motivated by the earlier experimental results and \textit{ab initio} studies on the electronic structure of layered ruthenates (Sr $_{2}$ RuO $_{4}$ and Ca $_{2}$ RuO $_{4}$ ) we introduce and in…

Stripe Phases in Layered Nickelates

Krzysztof Rościszewski, Andrzej M. Oleś

To describe quasi two-dimensional nickelates we introduce an effective Hamiltonian for $e_{g}$ electrons which includes the kinetic energy, on-site Coulomb interactions, spin-spin an…
