概要

Thin films of YBa_2Cu_3O_<7-x>(YBCO) were irradiated with 0.5 and 2.5 MeV 0+ ions in the fluence range of 3×10^<14> to 3×10^<19> m^<-2>. Above 1018 m^<-2>, the critical tem perature (T_e) and crystaninity degraded, and the elec trical resistivity and c axis lattice constant increased, while no significant change was observed below the fluence. In the fluence range of 1×10^<15> to 1×10^<16>m^<-2> enhancement less than 10% was observed in transport critical current density (Je)
