Evolution of crystal field and intraionic interactions in the ilmenite $A$ IrO $_{3}$ ( $A$ = Mg, Zn, Cd) and hyperhoneycomb $β$ -ZnIrO $_{3}$

Yuya Haraguchi, Hiroko Aruga Katori, Kenji Ishii +1

Spin-orbit Mott insulators with the $t_{2 g}^{5}$ electron configuration are promising platforms for the Kitaev spin liquid, yet fine-tuning of their crystal structures is essential t…
