Abstract

The effects of Ar ion implantation on superconductivity and structural changes in epitaxial YBa₂Cu₃O_7-x thin films have been studied using x-ray diffraction, scattering electron microscopy (SEM), and transmission electron microscopy (TEM). It was found that both the critical current density J_c and the superconducting transition temperature T_c significantly decreased with the fluence. The sample went through the metal to semiconductor to insulator transitions with the increase of fluence. The TEM images showed that the sample implanted with high fluence became amorphous.
