Abstract

• We report the effect of ?-particle irradiation on the reduction of the critical temperature Tc of a NdFeAs(OF) single crystal. Our data indicate that irradiation defects cause both nonmagnetic and magnetic scattering, resulting in the Kondo-like excess resistance ??ðTÞ / lnT over 2 decades in temperatures above Tc. The critical density of magnetic irradiation defects which suppresses Tc is found to be much higher than those for cuprates and multiband BCS superconductors. We suggest that such anomalously weak pair breaking by irradiation defects indicates that magnetic scattering in pnictides is coupled with pairing interactions mediated by spin fluctuations.
