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