Initial Transport Measurements for Rare Earth-Based Topological Material Candidate

Magnetic topological semimetals are notable for possessing remarkable transverse transport properties, large non-saturating magnetoresistance, and anomalous spin textures. The LnSbTe family of materials, where Ln is in the Lanthanide series, are well-known magnetic topological nodal line semimetals crystallizing in the tetragonal ZrSiS-type structure. Here we study a new related compound featuring a slight monoclinic distortion, the effect of which is expected to modify the pertinent symmetries involved in the topological characteristics of the material.
