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