Abstract

Melt-powder melt-grown samples with different amounts of artificially introduced 211 particles were exposed to fast neutron irradiation up to a fluence of 4 × 10²¹ m^-2 (E > 0.1 MeV). The influence of the irradiation on the critical current characteristics and on the irreversibility lines is investigated. Shifts of the irreversibility lines and enhanced critical current densities are observed. The results are compared with similar experiments on high quality single crystals.
