${\mathrm{Sr}}_{2}{\mathrm{MoO}}_{4}$ is isostructural to the unconventional superconductor ${\mathrm{Sr}}_{2}{\mathrm{RuO}}_{4}$ but with two electrons instead of two holes in the $\mathrm{Mo}/\mathrm{Ru}\text{\ensuremath{-}}{t}_{2g}$ orbitals. Both materials are Hund's metals, but while ${\mathrm{Sr}}_{2}{\mathrm{RuO}}_{4}$ has a van Hove singularity in close proximity to the Fermi surface, the van Hove singularity of ${\mathrm{Sr}}_{2}{\mathrm{MoO}}_{4}$ is far from the …
