摘要：

A strong correlation of the decoupling temperature (T(d)) with applied magnetic field (h) and oxygen stoichiometry (delta) of Tl2Ba2Ca2Cu3O10-delta is reported. The decoupling temperature has been deduced from the disappearance of the intergranular screening currents and is found to obey the following relationship with the amplitude h0 of the external magnetic field, h (t) = h0 sin 2f t. ; T(d) = 110.54 - 1.17h0 + 0.026h0(2) for a delta = 0.009 sample and T(d) = 98.09 - 2.25h0 + 0.06h0(2) for a delta = 0.141 sample. Both the decoupling temperature (T(d)) and the intragrain superconducting transition temperature (T(c)) decrease with oxygen deficiency (delta), and the former characteristic temperature has a much stronger dependence on delta than the latter.
