Gamma radiation resistance of the high <i>T</i> <i>c</i> superconductor YBa2Cu3O7−δ

Abstract

Exposure of the high Tc superconductor YBa2Cu3O7−δ to 60Co γ irradiation up to 1.3 Mrad is found to have virtually no effect on its superconductive properties as measured by a novel variant of the microwave absorption method.
