Abstract

The effects of neutron irradiation on the superconducting properties of HgBa2CuO4+δ are reported. Enhancements in the magnetization critical current density (Jc), as calculated by the Bean model, vary with magnetic field and temperature and range from 1-2 orders of magnitude. Large values (Jc>104 A/cm2) are obtained above (0.5 T, 77 K) and (3 T, 50 K) after irradiation. A large shift in the irreversi- bility line toward higher field and temperature is also reported. These results demonstrate that HgBa2CuO4+δ is not intrinsically limited to low current density and may become a technologically important compound.
