Abstract

Irradiation effects of 120 MeV oxygen-ion beam on Bi2Sr2CaCu2Oy (BSCCO) single crystal were investigated with a fluence of 3×1014cm−2. Critical current density (J c) calculated from magnetization loops was enhanced in the temperature range of 20 to 77 K, with a typical value of 200 in enhancement ratio at 40 K and 0.1 T. In comparison with those after electron, neutron and heavy-ion irradiations previously reported, the magnetic field dependence of J c after the oxygen-ion irradiation was the most similar to that after the neutron irradiation.
