Structure symmetry determination and magnetic evolution in $\mathrm{S}{\mathrm{r}}_2\mathrm{I}{\mathrm{r}}_{1-\mathrm{x}}\mathrm{R}{\mathrm{h}}_{\mathrm{x}}{\mathrm{O}}_4$

Abstract

We use single-crystal neutron diffraction to determine the crystal structure symmetry and the magnetic evolution in the rhodium doped iridates $\mathrm{S}{\mathrm{r}}_2\mathrm{I}{\mathrm{r}}_{1-\mathrm{x}}\mathrm{R}{\mathrm{h}}_{\mathrm{x}}{\mathrm{O}}_4$ ($0\le x\le 0.16$). Throughout this doping range, the crystal structure retains a tetragonal symmetry (space group $I{4}_1/a$) with two distinct magnetic Ir sites in the unit cell forming staggered $\mathrm{Ir}{\mathrm{O}}_6$ rotation. Upon Rh doping, the magnetic order is suppressed and the magnetic moment of Ir${}^{4+}$ is reduced from 0.21 ${\mu }_{\mathrm{B}}$/Ir for $x=0$ to 0.18 ${\mu }_{\mathrm{B}}$/Ir for $x=0.12$. The magnetic structure at $x=0.12$ is different from that of the parent compound while the moments remain in the basal plane.
