Fig. 3: Evolution of superconductivity in β-ThRh1−xIrxGe.
a–c Low-temperature resistivity, magnetic susceptibility and specific heat, respectively, for the β-ThRh1−xIrxGe samples with x ≤ 0.5. The vertical dashed line indicates the Tc for x = 0.5, and the solid lines in (c) are fits to the normal-state data by the Debye model. d–f Same set of data for the samples with x ≥ 0.5. The vertical dashed line indicates the Tc for x = 0.9. g–i Normalized electronic specific-heat data plotted as a function of temperature for the samples with x = 0.2, 0.5, and 0.6, respectively. In (a, b), the solid lines are entropy conserving constructions to estimate the size of specific-heat jump. In (c), the solid curve is a fit to the data by the α-model with α = 2.0.
