Recently, nickelates and ruthenates (3d and 4d oxides) have been extensively explored for new superconductors in addition to copper oxides, where high pressure or epitaxy is utilized to achieve nonequilibrium phases. We are engaged in platinates (5d oxides) using molecular beam epitaxy. We report on the growth of ~40 nm-thick epitaxial PtO₂ films with the CaCl₂ structure and their metallic conductivity.
