摘要：

Magnetization measurements were performed as a function of magnetic field and time in Tl2Ba2CaCu2O8 and TlBa2CaCu2O7 single crystals to study the effects of high energy Xe ion irradiation. The effective pinning-energies at 6 K and 40 K have been evaluated from magnetic relaxation measurements. The activation energies are hardly changed after irradiation. The study of magnetization hysteresis shows that an irradiation fluence of 2 x 10(11) ions cm-2 enhanced hysteresis at 6 K in both crystals. But a fluence of 10(12) ions cm-2 was detrimental for the 2212 sample which is the most sensitive to heavy ion irradiation damage in the Tl-cuprate family. The magnetic hysteresis at 70 K after irradiation is more drastically increased than at 6 K. This spectacular modification is interpreted by a recovery of the 3D character of the flux line lattice.
