Δλi(T) normalized by λi(0) for i = a, b, and c as a function of T/Tc for crystals #A1 (a), #B1 (b), and #C1 (c). Solid lines in a-c represent the fitting curves of the power-law function and the obtained exponent values are shown in the figures. The inset shows the same data plotted against \({(T/{T}_{c})}^{2}\), and the black dashed lines represent T2 dependence. Normalized superfluid density calculated from Δλi(T)/λi(0) data for crystals #A1 (d), #B1 (e), and #C1 (f). Solid and dashed lines represent the theoretical curves for the single order parameter case for js parallel and perpendicular to the nodal direction I, respectively.
