Motivated by the recent discovery of high-temperature antiferromagnet ${\mathrm{SrRu}}_{2}{\mathrm{O}}_{6}$ [Hiley et al., Angew. Chem. Int. Ed. 53, 4423 (2014); Tian et al., arXiv:1504.03642] and its potential to be the parent of a new superconductor upon doping, we construct a minimal ${t}_{2g}$-orbital model on a honeycomb lattice to simulate its low-energy …
