The electronic structure of various nickel oxides with nickel valence varying from 1+ to 3+ was investigated with the aim to find similarities and differences to the isoelectronic cuprates. Only if the Ni ions are forced into a planar coordination with the O ions can a $S=1/2$ magnetic insulator be realized with the difficult ${\mathrm{Ni}}^{+}$ oxidation state and possibly doped with low spin $(S=0){\mathrm{Ni}}^{2+}$ holes directly analogous to the superconducting cuprates. The more common…

Electronic structure of rare-earth infinite-layer RNiO2(R=La,Nd)
The discovery of infinite-layer nickelate superconductor marks the new era in the field of superconductivity. In the rare-earth ($R$) nickelates $\mathrm{RNi}{\mathrm{O}}_{2}$, although the Ni is
A "road-map" of Nickelate superconductivity
We comment on the electronic structure of Nickelate system $Nd Ni O_2$ which shows superconductivity on doping. The doped system $Nd_{0.8}Sr_{0.2}NiO_2$ shows (most probably unconventional)
Charge Dynamics in Layered Nickelates with Charge-Ordering Instability
A layered nickelate R\(_{2-\mathrm{{x}}}\)Sr\(_{x}\)NiO\(_{4}\) is atypical electron-correlated system with charge-ordering instability, and also has long been known as a counterpart material with
Self-doped Mott insulator for parent compounds of nickelate superconductors
Motivated by analyses of the reported electrical resistivity and Hall coefficient data in the normal state, the authors propose that the parent compound of the newly discovered superconducting
Two-band model for magnetism and superconductivity in nickelates
The recently discovered superconductivity in Nd$_{1-x}$Sr$_x$NiO$_2$ provides a new opportunity for studying strongly correlated unconventional superconductivity. The single-hole Ni$^+$ ($3d^9$)
A possible family of Ni-based high temperature superconductors
We suggest that a family of Ni-based compounds, which contain [Ni$_2$M$_2$O]$^{2-}$(M=chalcogen) layers with an antiperovskite structure constructed by mixed-anion Ni complexes, NiM$_4$O$_2$, can be
Exchange interactions and sensitivity of the Ni two-hole spin state to Hund's coupling in doped NdNiO2
The discovery of superconductivity in Nd${}_{1\ensuremath{-}x}$Sr${}_{x}$NiO${}_{2}$ has resulted in a flurry of experimental and theoretical work to understand the nature of nickelate
Electronic structure of the parent compound of superconducting infinite-layer nickelates
X-ray spectroscopy and density functional theory are used to show that the electronic structure of the parent compound of superconducting infinite-layer nickelates, while similar to the copper-based high-temperature superconductors, has significant differences.
Layered palladates and their relation to nickelates and cuprates
We explore the layered palladium oxides La$_2$PdO$_4$, LaPdO$_2$ and La$_4$Pd$_3$O$_8$ via ab initio calculations. La$_2$PdO$_4$, being low spin $d^8$, is quite different from its high spin nickel

We study the electronic structure of $\mathrm{La}\mathrm{Ni}{\mathrm{O}}_{3\ensuremath{-}x}$ thin films using in situ soft x-ray photoemission and absorption spectroscopy. The in situ high-resolution
