Abstract

SmFeAsO $_{1-x}$ F $_x$ was irradiated in a fission reactor to a fast (E > 0.1 MeV) neutron fluence of 4x10^ ${21}$ m $^{-2}$ . The introduced defects increase the normal state resistivity due to a reduction in the mean free path of the charge carriers. This leads to an enhancement of the upper critical field at low temperatures. The critical current density within the grains, Jc, increases upon irradiation. The second maximum in the field dependence of Jc disappears and the critical current density becomes a monotonically decreasing function of the applied magnetic field.
