Abstract
The ZrSiS-type materials have attracted intensive attention due to the existence of various topological fermions. The magnetic version of the ZrSiS-type materials, $\mathit{Ln}\mathrm{SbTe} (Ln=\mathrm{lanthanides})$, is an ideal candidate to explore novel exotic states due to the interaction between magnetism and topology. In this work, we report the experimental study on structural, magnetic, thermodynamic, and electronic properties for $\mathrm{Sm}{\mathrm{Sb}}_{x}{\mathrm{Te}}_{2\ensuremath{-}x}$ with various Sb content. The revealed evolutions of these properties with tuning the compositions would provide useful insights for the fundamental topological physics and the future applications.
