We report on the study of insulator-to-metal transition in post-perovskite compound CaIrO3. It is discovered that a gradual chemical substitution of calcium by yttrium leads to the onset of strong metallic behavior in this compound. This observation is in stark contrast to BaIrO3, which preserves its Mott insulating behavior despite excess of the charge carriers due to yttrium doping. Magnetic measurements reveal that both compounds tend to exhibit magnetic character irrespective of the…

High-temperature weak ferromagnetism on the verge of a metallic state: Impact of dilute Sr doping on BaIrO3
The 5d-electron based BaIrO3 is a nonmetallic weak ferromagnet with a Curie temperature at Tc=175 K. Its largely extended orbitals generate strong electron-lattice coupling, and magnetism and

CaIrO3: a spin-orbit Mott insulator beyond the j(eff) ground state.
It is concluded that insulating CaIrO3 is not a j(eff) = 1/2 iridate and the consequences of this finding to the interpretation of previous experiments are discussed, as well as how the Mott insulating state in iridates can be readily extended beyond the j(EFF) =1/2 ground state.
Origin of charge density wave formation in insulators from a high resolution photoemission study of BaIrO3.
The energy dependence of the spectral density of states reveals the importance of magnetic interactions, rather than well-known Coulomb repulsion effect, in determining the electronic structure thereby implying a close relationship between ferromagnetism and CDW observed in this compound.

Orbital magnetism and spin-orbit effects in the electronic structure of BaIrO3.
The electronic structure and magnetism of Ir 5d5 states in nonmetallic, weakly ferromagnetic BaIrO3 are probed with x-ray absorption techniques and the unusual, atomiclike nature of the 5d moment is driven by a strong spin-orbit interaction in heavy Ir ions.

It is demonstrated that the deviation from the ideal Jeff=1/2 state is negligible at short time scales for both single- and double-layer iridates, while it becomes quite significant for Sr3Ir2O7 at long times and low energy.

Results demonstrate that MgSiO3 perovskite transforms to a new high-pressure form with stacked SiO6-octahedral sheet structure above 125 gigapascals and 2500 kelvin (2700-kilometer depth near the base of the mantle) with an increase in density of 1.0 to 1.2%.
Resonant x-ray diffraction study of the strongly spin-orbit-coupled mott insulator CaIrO3.
It is proposed that nonmagnetic resonant scattering is a powerful tool for unraveling an orbital state even in a metallic iridate, points to the universal importance of the spin-orbit coupling in Ir oxides, independent of the octahedral connectivity and lattice topology.
