Nonreciprocal transport at high magnetic fields. a The magnetic field dependence of first harmonic resistance R^ω at T = 9.5 K (light blue) and T = 10 K (gray) measured under I = 200 μA. b The magnetic field dependence of second harmonic resistance R^2ω. at T = 9.5K and T = 10 K measured under I = 200 μA. The red and blue triangles represent the positive and negative peaks at around B = 2 T and B = 9 T, respectively. c The contour plot of R^ω in the plane of magnetic field and temperature at θ = 90° (B || y, defined in f) measured under I = 200 μA. The superconducting onset and R = 1 Ω are shown in circle and triangle, respectively. d The contour plot of R^2ω in the plane of magnetic field and temperature at θ = 90° measured under I = 200 μA. e The in-plane magnetic-field direction dependence of R^2ω at B = 2 T (red) and B = 9 T (blue) within xy plane measured under I = 200 μA. φ is defined as an angle in xy plane measured from the x-axis. f The out-of-plane magnetic-field direction dependence of R^2ω at B = 2 T (red) and B = 9 T (blue) within zy plane measured under I = 200 μA. θ is defined as an angle in zy plane measured from the z-axis. g The contour plot of R^2ω in the plane of magnetic field and temperature at θ = 70° measured under I = 200 μA
