Figure 8: Strong coupling calculation of Hc2 in URhGe.
From: Pairing mechanism in the ferromagnetic superconductor UCoGe

Blue squares: data of Hc2//b in URhGe from ref. 45. Full lines: series of calculations of Hc2 with fixed values of the strong coupling constant λ, which changes from 0.7 to 1.5 by steps of 0.05. Ω and have been adjusted so as to match the experimental Tsc and initial slope for λ=0.75 and μ*∼0.1. Note that if λ had, in zero field, the value it reaches at HR
, Tsc would be of order 0.67 K instead of 0.26 K.
