Temperature dependence of θ₂ and R₂/R₀ as defined in the main text for the x = 0.065 samples. (a) and (b) are obtained by the two-end-points method, while (c) and (d) are obtained by the grease method. All the measurements are taken at 9 Tesla. The green and cyan dashed lines represent antiferromagnetic transition and structural transition temperatures, respectively. The black squares and red circles represent current following along the tetragonal (110) and (100) directions, respectively.
