High-pressure versus isoelectronic doping effect on the honeycomb iridate Na${}_2$IrO${}_3$

V. Hermann, J. Ebad-Allah, F. Freund +7

We study the effect of isoelectronic doping and external pressure in tuning the ground state of the honeycomb iridate Na${}_2$IrO${}_3$ by combining optical spectroscopy with synchrotr…
