Synthesis and Investigations of the Kondo Lattice Compound CeSbS*

Recent work reveals intriguing behavior in the family of layered tetragonal materials that crystallize with the formula LnSbCh (Ln = lanthanide and Ch = chalcogenide). CeSbTe has been investigated as a possible host for topologically protected electronic states [1] and CeSbSe exhibits complex magnetic ordering at T_M = 3 K, where the application of a magnetic field results in a cascade of magnetically ordered states [2]. Inspired by these results, we have synthesized a variety of f-electron analogues where Ln = La, Ce, and Yb and Ch = S, Se, and Te. We report these results and focus on the electrical transport and magnetic properties of CeSbS, which is the volume compressed analogue to CeSbSe.
