Disorder-Induced Pair Breaking in Superconductors

Lemberger, Thomas R. / Lee, Soon-Gul

Abstract By enhancing thermal supercurrent fluctuations, disorder can cause significant pair-breaking effects on the transition temperature, density of states, and order parameter in superconductors. We have observed this pair-breaking mechanism in two-dimensional Aℓ films by using a novel tunneling technique. A crude model explains the results rather well. An extension to 3 dimensions of that model is used below to estimate pair- breaking rates in Heavy-Fermion and High-Tc compounds. We find that the disorder-induced pair-breaking rates are likely to be significant.
