ملخص

Specimens of Tl₂Ba₂Ca₂Cu₃O₁₀ tapes were prepared using the powder in tube method. The voltage-current (V-I) characteristics were used to study the temperature and magnetic field dependence of the critical current density J_c(T, B). Obtained results confirmed the high sensitivity of the superconducting tape to the applied magnetic field and are explained based on the weak links and Josephson junctions between the grains. The temperature dependence of J_c was also derived and discussed in terms of the thermally activated flux flow (TAFF). The effect of gamma irradiation on the critical current density J_c(T, B) was also studied up to a gamma dose of 400 MR. Gamma irradiation was found to increase J_c at relatively low temperature and magnetic field ranges. Therefore, gamma irradiation is a useful method to improve the superconductivity of the Tl₂Ba₂Ca₂Cu₃O₁₀ tapes.
