Magneto-Transport and Shubnikov-de Haas Oscillations in the Type-Ⅱ Weyl Semimetal Candidate NbIrTe4 Flake

         

摘要

We report on magnetoresistance,Hall effect,and quantum Shubnikov-de Haas oscillation (SdH) experiments in NbIrTe4 single crystals,which was recently predicted to be a type-Ⅱ Weyl semimetal.NbIrTe4 manifests a non-saturating and parabolic magnetoresistance at low temperatures.The magneto-transport measurements show that NbIrTe4 is a multiband system.The analysis of the SdH oscillations reveals four distinct oscillation frequencies.Combined with the density-functional theory calculations,we show that they come from two types of Fermi surfaces:electron pocket E1 and hole pocket H2.
