摘要：

We have investigated the effect of Li2CO3 addition on the transport and magnetic properties of Bi1.7Pb0.4Sr1.5Ca2.5Cu3.6Ox, samples in connection with the structural changes observed by scanning electronic microscopy (SEM) and X-ray diffraction. In addition to the results reported in literature, we have extracted new information from the magnetic hysteresis loops and AC susceptibility measurements. One such information is the splitting of the AC loss peak corresponding to the dissipation inside the Bi-2223 grains. The results reported here have been compared with those obtained for Bi1.7Pb0.4Sr1.5Ca2.5Cu3.6Ox/(LiF)(y) and Bi1.7Pb0.4Sr1.5Ca2.5Cu3.6Ox/(LiCl)(y) specimens, and the effect of halogen is pointed out.
