Chemical tuning between triangular and honeycomb structures in a 5$d$ spin-orbit Mott insulator

R. D. Johnson, I. Broeders, K. Mehlawat +4

We report structural studies of the spin-orbit Mott insulator family K${}_x$Ir${}_y$O${}_2$, with triangular layers of edge-sharing IrO${}_6$ octahedra bonded by potassium ions. The potass…
