A systematic study of the weak link behavior for (Bi,Pb) 2 Sr 2 Ca 2 Cu 3 O y (Bi-2223) polycrystalline samples has been done using the electrical resistivity and AC susceptibility techniques. In this project, we have prepared a series of Bi-2223 samples with different fractions of Bi-2212 phase and
We studied the effect of Ba substitution of Sr on magnetic Jc properties and irreversibility line of single phase (Bi,Pb)2Sr2Ca2Cu3Oy superconductors. We found from field dependence of the magnetic Jc that the Ba substitution of 10% Sr resulted in maximal improvement on magnetic Jc and irreversibili
