a, b Differential resistance versus bias current and magnetic field for θ = 0° and 90°, respectively. The temperature is 160 mK, and the color bar represents the magnitude of the differential resistance. c The in-plane angle dependence of the magneto-resistance shows the two-fold symmetry, where θ = 0° denotes that the magnetic field is applied along the current direction and θ = 90° denotes the magnetic field is perpendicular to the current direction. The temperature is 160 mK. d The in-plane angle-dependent critical magnetic field μ0Hc at different temperatures also shows the characteristic two-fold anisotropy.
