Ilmenite-Type Ca${}_x$IrO${}_3$ via Topochemical Ion Exchange: Stacking Faults and Low-Temperature Magnetic Anomaly

Haruki Kira, Yuya Haraguchi, Wataru Yokoshima +2

We report the synthesis of an ilmenite-type polymorph of Ca${}_x$IrO${}_3$ distinct from the known post-perovskite and perovskite phases, via low-temperature topochemical Ca${}^{2+}$/2Na…
