The magnetism in the saw-tooth lattice of Mn in the olivine chalcogenides, Mn$_2$SiS$_{4-x}$Se$_x$ ($x$ = 1$\textendash$4) is studied in detail by analyzing their magnetization, specific heat and thermal conductivity properties and complemented with density functional theory calculations. The air-stable chalcogenides are antiferromagnets and show a linear trend in the transition temperature, $T_N$ as a function of Se-content ($x$) which shows a decrease from $T_N \approx$ 86~K for {\mss} to 66…
