The ability to tune the iron chalcogenides ${\mathrm{BaFe}}_{2}{Q}_{3}$ from Mott insulators to metals and then superconductors with applied pressure has renewed interest in low-dimensional iron chalcogenides and oxychalcogenides. We report here a combined experimental and theoretical study on the iron oxychalcogenides ${\mathrm{BaFe}}_{2}{Q}_{2}\mathrm{O}\phantom{\rule{4pt}{0ex}}(Q=\mathrm{S},\text{Se})$ and show that their magnetic behavior results from …
