Abstrakt: The Bi1.4Pb0.6Sr2Ca2Cu3O10ceramic was irradiated with 1 MeV electrons of 1.1-27.5×1011cm-2·s-1dose rate to a dose of 1.0×1015cm-2at ambient temperature, and the magnetization measurements were carried out at 5, 20 and 50 K in magnetic fields up to 5 T. Whereas the magnetization current density at 5 and 20 K was increased by the irradiation, the current density measured at 50 K was decreased in low magnetic fields. The enhancement of 17-25% in the current density at 5 K, which was dependent on dose rate, changed slightly with an increase in strength of the magnetic field.
