Abstract

We investigated the electrical modifications induced by hard X-ray synchrotron radiation on the YBa₂Cu₃O_7-δ 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 nonsuperconducting high resistance state is observed. These results pave the way to the realization of electrical devices by Xray nanopatterning on this kind of oxide, extending the previous studies on Bi₂Sr₂CaCu₂O_8+δ.
