Description

Bi2.4- xPb xSr2CaCu2O y crystals with x=0.05, 0.1 and 0.2 were irradiated with 60Co γ -rays of 0.6 MR/h up to a dose of 64.8 MR at room temperature. For all the irradiated samples with x=0.05, 0.1, the superconducting transition temperature T c increased after γ -ray irradiation, while the T c of irradiated samples with x=0.2 increased at lower doses, and then decreased at 64.8 MR. X-ray photomission spectroscopy results reveal that higher oxidation states of Bi and Cu occurred in the sample irradiated with 64.8 MR. The dependence of T c on γ -ray irradiation dose can be explained in terms of the change of valence state of Bi and Cu.
