Abstract

An excellent tool to enhance the critical current density in superconductors is the controlled introduction of defects by irradiation damage. Irradiation with 2.65 GeV Au ions provides the generation of amorphous line defects. Polycrystalline (Bi, Pb)2Sr2Ca2Cu3O10 + δ Ag tapes processed by the powder-in-tube technique were irradiated up to doses of 3.5× 1011 Au ions/cm2 at a temperature of 100 K. On the one hand, our irradiation experiments were performed to investigate the degree ofj c enhancement and, on the other hand, to examine the flux pinning mechanism in (Bi, Pb)2Sr2Ca2Cu3O10 + δ tapes. Characterization of the samples was performed by magnetization measurements using a vibrating sample magnetometer (VSM) up to 13 T in a temperature range between 5 and 100 K. Further, we have measured the relaxation of the magnetic moment before and after irradiation to determine the influence of columnar defects on the activation energyU. A comparison of the irradiation-induced effects with previous results obtained on Bi2Sr2CaCu2O8 + δ irradiation experiments is included.
