Fig. 4: Anisotropic magnetoresistance in PtSe2.

a Magnetoresistance \(\Delta \rho /\rho _0\) measured in the PtSe2 sample along a and a′ (t = 32 nm). Inset: Microscopic photo of two devices made on the same flake with current \(I\parallel a^{\prime}\) (down) and \(I\parallel a\) (up), respectively. Blue dashed arrows mark the orientations of a, solid arrows show the current direction. Scale bar: 2 μm. b Resistivity \(\rho\) corresponding to the magnetoresistance data plotted in a. c Angular dependence of the magnetoresistance measured in a PtSe2 sample with \(I\parallel a^{\prime}\) (t = 29.8 nm). Inset: Microscopic photo of the measured device. The blue dashed arrow marks the orientations of a. The dark solid arrow shows the tilted magnetic field B misaligned from I by the angle of θ. Scale bar: 5 μm.
