Abstract
The effects of gamma irradiation on the superconducting properties of GdBa2Cu3O7-x have been investigated. No significant changes in the superconducting transition temperature Tc or the normal-state resistivity could be ascribed to the gamma irradiation, irrespective of the ambient gas, for gamma doses up to 1.8 × 1010 rad. This result contradicts two previous studies reported in the literature. Reasonable explanations for these discrepancies were developed based on the observed inherent sample-to-sample variations of Tc or the normal-state resistivity, the extreme sensitivity of these materials to inadvertent heating at temperatures as low as 200°C, and the tendency of these ceramics to develop microcracks with thermal cycling.
