High-pressure synthesis of Ba${}_2$RhO${}_4$, a rhodate analogue of the layered perovskite Sr-ruthenate

I. Kurata, José A. Flores-Livas, H. Sugimoto +6

A new layered perovskite-type oxide Ba${}_2$RhO${}_4$ was synthesized by a high-pressure technique with the support of convex-hull calculations. The crystal and electronic structure we…
