Anisotropic transport and de Haas$-$van Alphen oscillations in quasi-one-dimensional TaPtTe${}_5$

Abstract

Because of the unique physical properties and potential applications, the exploration of quantum materials with diverse symmetry-protected topological states has attracted considerable interest in the condensed-matter community in recent years. Most of the topologically nontirvial materials identified thus far have two-dimensional or three-dimensional structural characteristics, while the quasi-one-dimensional (quasi-1D) analogs are rare. Here we report on anisotropic magnetoresistance, Hall effect, and quantum de Haas$-$van Alphen (dHvA) oscillations in TaPtTe${}_5$ single crystals, which possess a layered crystal structure with quasi-1D PtTe${}_2$ chains. TaPtTe${}_5$ manifests an anisotropic magnetoresistance and a nonlinear Hall effect at low temperatures. The analysis of the dHvA oscillations reveals two major oscillation frequencies (63.5 T and 95.2 T). The corresponding light effective masses and the nonzero Berry phases suggest the nontrivial band topology in TaPtTe${}_5$, which is further corroborated by the first-principles calculations. Our results suggest that TaPtTe${}_5$, in analogy with its sister compounds TaPdTe${}_5$ and TaNiTe${}_5$, is another quasi-1D material hosting topological Dirac fermions.
