Fig. 5: Control experiment of ρc(θ) curves with twofold symmetry of in another sample.

From: Twofold symmetry of c-axis resistivity in topological kagome superconductor CsV3Sb5 with in-plane rotating magnetic field

Fig. 5

a,b Angular dependence of c-axis resistivity measured at different in-plane magnetic field shown by a rectangular and a polar coordinate, respectively. The inverse of the local extrema can be observed when the magnetic field crosses about 2 T. c FT result to the ρc(θ) curve measured at 7 T. d Temperature dependence of the nematicity. The solid symbols are derived from the c-axis resistivity difference between θ = 0° and 90° at 0.4 and 5 T, while the open symbols show twice the amplitude of the 180° (or C2) peak (2AFT,C2) from FT results (Supplementary Fig. 8c) to ρc(θ) curves measured at different temperatures under 5 T. The error bars in the figure are determined by the noise in the resistivity measurement and the error transfer theory. The relatively small thickness and large surface area make the resistance very small with a relatively large noise.
