Effect of Thermal Phonon Pair Breaking on Superconducting Fluctuations

Abstract

Previous experimental measurements of the paraconductivity for various materials show varying degrees of agreement with the Aslamazov-Larkin theory. Our measurements indicate that this behavior can be understood if one includes the Maki-Thompson fluctuation term with a thermal pair-breaking interaction plus an additional pair-breaking parameter proportional to the resistance per unit area of the film.
