    Notes: Abstract The effect of thermal and epithermal neutron irradiation on the superconducting critical temperature and critical current density of some Li-doped YBa2Cu3O7−x samples was studied. The critical temperature exhibits a peak and the critical current density a valley in their dependence on neutron fluence, for moderate dose. A simple model, based on the Van Hove scenario and the kinetics of the defect production, is used to describe both phenomena.

    Notes: Abstract The effects of neutron irradiation on the critical temperature and critical current density at 77 K and zero magnetic field of high-temperature superconductors was studied in Li-doped YBa2Cu3O7−x . Damage and thermal neutron reactions with Li produce an insignificant increase of the critical temperature for Li inserted as flame-melted Li2CuO2 while for the others it remains nearly unaffected. The critical transport current density of the sintered YBa2Cu3O7−x remains unaffected for samples with Li2CuO2 and shows a decrease for LiFdoped samples.
