Detailed study of the thermodynamics of a superconductor with paramagnons

  • Published:
Journal of Low Temperature Physics Aims and scope Submit manuscript

The effect of paramagnons on the thermodynamics of a superconductor has been studied within Eliashberg theory. For model microscopic parameters approximating those characteristic of Nb we compare results for finite and zero paramagnon mass enhancement parameter, λspin. The change obtained in the thermodynamics is significant, but because of present uncertainties in the experimental data and in the value of the calculated electron-phonon interaction, an accurate value of λspin cannot be determined. The effect of spin fluctuations on the quasiparticle density of states in the region of phonon energies is also investigated. Our results have implications for tunneling inversion.
