    • c. The specific heat discontinuity has been chosen to match the maximum in the experimental data. Theoretical values depend on the symmetry of the order parameter. Typical values in a weak-coupling theory, which are universal, are on the order of 1.2-1.4 (i.e., much larger than the height of the observed feature); in strong-coupling theories they are not universal [18].

    • note
    • This choice of the orbital structure of the gap function is arbitrary. If experimental evidence should favor a different structure, the theory can be easily adjusted to that.

    • note
    • A ferromagnetic superconductor should have an intrinsic nonzero specific heat coefficient, in analogy to the specific heat in the vortex phase of an ordinary type-II superconductor [21]. We neglect this effect whose size depends on details of the superconducting phase that are not known.
