ac complex susceptibility, χ′ and χ″, dc magnetization and electrical resistivity of sintered superconductors Bi–Pb–Sr–Ca–Cu–O and Y–Ba–Cu–O have been measured. The results show two non-linear 2/3 power behaviors: field dependence of χ″ peak temperature, a quasi de Almeida-Thouless line, and a irreversibility line. The former corresponds to the property of intergrain material measured at low field, it can be interpreted by superconductive glass state in high-T c superconductor and/or the weakly connected loop model. The latter corresponds to the property of intragrain material measured at higher field, it can be interpreted by the thermally activated flux creep model. Moreover, the field dependences of width and height of χ″ peak are also exhibited. Finally, we have measured the I – V characteristics at 103.8 K for Bi–Pb–Sr–Ca–Cu–O sample and suggested the relation between the χ″ peak temperature and the zero dissipation temperature.
