The effect of gamma irradiation on the superconducting properties of GdBa2Cu3O7-x
- 1. Oak Ridge National Lab., TN (USA)
Description
The effects of gamma irradiation on the superconducting properties of GdBa2Cu3O7-x have been investigated. No significant changes in the superconducting transition temperature or the normal-state resistivity could be ascribed to the gamma irradiation, irrespective of the ambient gas, for gamma doses up to 1.8x1010 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 the transition temperature or the normal-state resistivity, the extreme sensitivity of these materials to inadvertent heating at temperatures as low as 200 deg.C, and the tendency of these ceramics to develop microcracks with thermal cycling. 9 refs.; 3 figs
