Abstract

Two post-perovskite oxides were discussed. One is CaPtO3, which is a new analog to the isostructural MgSiO3. By analyzing structural parameters, we elucidate the role of covalency in the post-perovskite compounds. The other is a new solid solution Ca1-xNaxIrO3 (0 ≤ x ≤ 0.37). This system exhibits a filling-control metal-insulator transition on a quasi-two-dimensional lattice. These studies indicate that the post-perovskite structure is an excellent playground to search novel electronic phases of strongly correlated electrons.
