Description

Epitaxially grown YBa2Cu3Ox films have been irradiated with 173 MeV 129Xe ions. A nonlinear decrease of the critical superconducting transition temperature and an exponential increase of the resistivity is observed. The c-axis parameter is extended to about 12 A with increasing Xe fluence and the twin boundaries disappear. The 1-2-3 phase is amorphized along the paths of the Xe ions within an area of 40 A in diameter. A defect-induced enhancement of the critical current density in magnetic fields is observed after low fluences only if the flux lines are aligned parallel to the amorphized ion traces
