Extended Data Fig. 4: In-plane measurements and quantum oscillations.
From: Three-dimensional quantum Hall effect and metal–insulator transition in ZrTe5
Measurement of SdH oscillations in ZrTe5 (sample 4) when a magnetic field is applied in the y direction. a–d, Coherent transport of ρxx (a, c) and ρzz (b, d). a, b, Schematic illustration of the setup with B//y and I//x (a) and with B//y and I//z (b). c, Longitudinal resistivity ρxx and Hall resistivity ρzx measured in the x–z plane, with magnetic field B//y and current I//x. c, d, ρxx and ρzz show similar oscillation patterns. Inset, zoom-in view of ρzz versus B. However, in zero magnetic field, the resistivity ρzz is about 30 times larger than ρxx.
