| 英文摘要 | 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 TaPtTe5 single crystals, which possess a layered crystal structure with quasi-1D PtTe2 chains. TaPtTe5 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 TaPtTe5, which is further corroborated by the first-principles calculations. Our results suggest that TaPtTe5, in analogy with its sister compounds TaPdTe5 and TaNiTe5, is another quasi-1D material hosting topological Dirac fermions. |
