Magnetic Topological Semimetal Phase with Electronic Correlation Enhancement in SmSbTe

The ZrSiS family of compounds hosts various exotic quantum phenomena due to the presence both topological nonsymmorphic Dirac fermions and nodal-line fermions. In this material family, LnSbTe (Ln= lanthanide) are particularly interesting owing intrinsic magnetism from magnetic Ln which leads new properties states. work, authors focus on previously unexplored compound SmSbTe. studies reveal a rare combination few functional in material, including antiferromagnetism with possible frustration, electron correlation enhancement, These enable SmSbTe as unique platform explore advanced functionalities arising interplay between magnetism, topology, electronic correlations.
