Description

We report the effects of heavy-ion irradiation on critical currents in (Y,Dy)Ba2Cu3O7−δ coated conductors made by a commercial metal organic deposition process. Irradiation with 185 MeV Au ions is investigated and contrasted with previous results on 74 MeV Ag ions. The change in critical current (Ic) is reported as a function of temperature (30–77 K), magnetic field (0–7 T) and magnetic-field angle (full angle dependence). Significant improvements are seen particularly at 30–40 K...[Show more]
