Abstract

We have studied the critical temperature Tc, upper critical field, and magnetotransport variation as a function of radiation damage in the low-Tc A15 superconductor Nb3Ir. We find a nonmonotonic variation in Tc with disorder and analyze these results in terms of the competition between density-of-states effects and weak localization. Magnetoresistance measurements confirm the presence of electron interaction effects associated with weak localization.
