(a) and (b) The temperature evolution of soft point-contact conductance curves G(V) as a function of the biased voltage for CeRu₂Al₁₀ with surface along b axis and an arbitrary direction, respectively. The curves are vertically shifted for clarity and the dashed lines are a guide for eyes to show the temperature evolution of the AFM gap Δ₁ and hybridization gap Δ_h, respectively. The arrows mark the position of the kink structure Δ₂ in the conductance curve G(V). (c) Temperature dependence of the extracted AFM gap Δ₁ for CeRu₂Al₁₀ in three crystallographic orientations in comparison with the standard mean-field BCS curves and the Δ₂ value for the kink structure also follows the BCS behavior.
