Magneto-transport measurements in ZrTe5. (a) Schematic drawing of the transport measurements. A constant current was applied along the a-axis. (b) Angle dependence of magnetoresistivity (MR) at 2.5 K. The Shubnikov–de Haas (SdH) oscillations are observed at different angles. (c) MR at different temperatures with θ=0°. The oscillations are not observable above 20 K. The inset is an enlarged view of the oscillations. (d) Landau fan diagram at θ=0°. The nontrivial Berry phase can be clearly seen. (e) Temperature dependence of the SdH oscillation amplitude at 1.34 T. (f) Dingle plot for the extraction of the scattering time.
