Abstract

Irradiation effects of low-dose (1014 n/cm2) neutrons on the resistance and AC susceptibility of multiphase YBa2Cu3O7 and Tl2Ca1Ba2Cu2O8 have been studied. Experimental results show that dispersed local superconducting regions in the samples may be unified to form a continuous percolating network using neutron irradiation. If the concentration of oxygen vacancies and interstitials is below or above an optimum value, the irradiation increases or decreases, respectively, the superconductive volume fraction and - via Cu-O bond length - the Tc value.
