Tuning the functional properties of YBa2Cu3O7-delta by synchrotron X-ray irradiation

Abstract : We investigated the electrical modifications induced by hard X-ray synchrotron radiation on the YBa2Cu3O7-delta high temperature superconductor. We explored two different irradiation regimes. At low X-ray doses a progressive shift of the critical temperature of the superconductor has been obtained. Conversely, increasing the X-ray dose, a transition to a non-superconducting high resistance state is observed. These results pave the way to the realization of electrical devices by X-ray nanopatterning on this kind of oxide, extending the previous studies on Bi2Sr2CaCu2O8+delta
