  The ZrSiS-type materials have attracted intensive attention due to the
existence of various topological fermions. The magnetic version of the
ZrSiS-type materials, LnSbTe (Ln = 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 SmSbxTe2-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.
