摘要：

Thallium-based single crystals (TlBa2Ca2Cu3O9 (Tl-1223), Tl2Ba2CaCu2O8 (Tl-2212) and Tl2Ba2Ca2Cu3O10 (Tl-2223)) have been exposed to Pb ions irradiation along the c-axis at fluences of 5 x 10(10) and 2 X 10(11) ions per cm(2). Reversible magnetization as a function of the field for different temperatures was measured in each compound for the two track densities. Two regimes are observed depending on the relative values of B and the dose equivalent field B Phi. They are explained in the framework of the London model taking into account the magnetic interactions between vortices and irradiation induced columnar defects.
