✦ Synopsis

Critical current densities have been inferred from magnetic hysteresis and volume pinning energies from magnetic relaxation measurements for neutron irradiated and unirradiated polycrystalline Y123 samples. Increases in the critical current densities, by factors of 2-3 in zero field and larger in a field, for the irradiated sample are observed. Large increases in the magnetic relaxation rate arealso observed at H = 1T. From the relaxation data and the amount of irreversible magnetization, pinning energies of 0.01-0.06 eV and 0.01-0.03 eV are inferred for the irradiated and unirradiated samples, respectively.
