Fig. 2: Angular and temperature dependences of the negative magnetoresistance.

From: Asymmetric Fermi velocity induced chiral magnetotransport anisotropy in the type-II Dirac semi-metal PtSe2

Fig. 2

a Angular dependence of the magnetoresistance \(\Delta \rho /\rho _0\) measured in a PtSe2 sample with the current \(I\parallel a\) (t = 29.8 nm) at tilted magnetic field B. Inset: Schematic showing the rotation of a sample by the angle of θ in B, where the rotation axis is perpendicular to the current. b Zoomed-in details of the negative magnetoresistance regime in a. c Magnetoresistance measured in a PtSe2 sample with \(B\parallel I\parallel a\) (t = 29.8 nm) at varied temperatures. d Inter-node relaxation time τ normalized with the value measured at T = 1.4 K, extracted from c. The error bars are much smaller than the data point and are not presented.
