Selective Octahedral Accommodation of Cr $^{3 +}$ and Weak Magnetic Connectivity in the Sugilite Analogue KNa $_{2}$ Cr $_{2}$ Li $_{3}$ Si $_{12}$ O $_{30}$

Yuya Haraguchi, Taishu Aoki, Daisuke Nishio-Hamane +1

We report the synthesis of the Cr analogue of sugilite, KNa $_{2}$ Cr $_{2}$ Li $_{3}$ Si $_{12}$ O $_{30}$ , in the milarite-type framework. Rietveld refinement of a composition-conserving antisi…

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…
