摘要：

We observed enhancement of critical current density (J(c)) with fast neutron irradiation in (Bi,Pb)2Sr2Ca2Cu3Oy (Bi2223) compound. The activation energies evaluated from the magnetic relaxation measurement suggest that the deeper pinning centers are introduced by the irradiation, which is consistent with the results of the distribution of the activation energies.
