Description

We report the effects of 200-keV He+-ion irradiation on the properties of high-quality YBa2Cu3O7-x thin films made in situ by pulsed-laser deposition. There is no significant change in Tc or the normal-state resistivity for fluences up to 1x1014 He+/cm2. There is only a small increase in the critical current density Jc measured at 60 K for fluences up to 3x1013 He+/cm2 and in nonzero magnetic fields. At fluences above 1x1014 He+/cm2, the induced changes are more rapid and have a deleterious effect on the superconducting properties
