The magnetization curves of neutron irradiated bulk YBa2Cu3Oy prepared by melt-textured growth method were measured from 1.5 to 85 K. Flux jumps were observed for H∥c at 6K. The anisotropies of critical current are analysed in detail- The pinning mechanism and physical model for flux jumps are discussed.
