Abstract
The influence of atomic disorder induced by irradiation with fast neutrons on the properties of normal and superconducting states of polycrystalline samples of FeSe has been studied. The irradiation with fluences of fast neutrons up to 1.25 × 1020 cm−2 at the irradiation temperature T irr ≈ 50°C leads to relatively small changes in the temperature T c of the superconducting transition and in the electrical resistivity ρ25 at 25 K. This behavior is related to the relatively low concentration of radiation defects arising at a given irradiation temperature, which is a consequence of a specific crystal structure of FeSe, which is more simple as compared to other layered compounds of this class.
