Abstract

We have performed magnetic susceptibility, heat capacity, neutron powder diffraction, and muon spin relaxation experiments to investigate the magnetic ground states of the $5 d^{2}$ double perovskites ${Sr}_{2} {YReO}_{6}$ and ${Sr}_{2} {InReO}_{6}$ . We find that ${Sr}_{2} {YReO}_{6}$ is a spin glass, while ${Sr}_{2} {InReO}_{6}$ hosts a nonmagnetic singlet state. By making detailed comparisons with other $5 d^{2}$ double perovskites, we argue that a delicate interplay between spin-orbit coupling, noncubic crystal fields, and exchange interactions plays a key role in the great variation of magnetic ground states observed for this family of materials.
