An experimental study of the magnetic irreversibility lines has been carded out on superconducting single crystals of Bi2\_,,Pb~Sr2CaCuO2Os, with and without lead. The irreversibility field values Bird(T) are almost identical for x= 0 and x= 0.4. However, the power-law fits of Bi~(T) ~ 1 / T" at low
This paper deals with the criteria to determine the irreversibility lines in Bi-2212 Ag sheathed wires through low frequency AC magnetic measurements and DC resistive measurements. In AC measurements the two components of wide band susceptibility versus temperature are measured at fixed DC field (in
