Figure 9: Adjustment of λ0 in URhGe.

Red circles: specific heat Sommerfeld coefficient for H//b from ref. 44, normalized to its value at zero field. Dark bue squares: ratio (1+λ(H))/(1+λ(0)) deduced from the calculations of Hc2 presented in Fig. 8 for λ(0)=0.75. Light blue squares: same ratio, but with the calculations of Hc2 for λ(0)=0.6. It shows that the amplitude of variation of the specific heat coefficient is a very selective criterium for the determination of λ(0) in this system. Inset: Corresponding variation of λ, for λ(0)=0.75.
