Abstract The ac resistivities and dc V-I characteristics have been studied in a multiphase Bi-Ca-Sr-Cu-O sample in the temperature region where the transition from the normal to the superconducting state takes place. The resistivity drops sharply between 112K and 107K and follows a tail before zero resistivity is reached near 94K. The resistivity in the tail region is current dependent, this current dependence is easily suppressed by a magnetic field. We argue that this phenomenon is due to weak links between regions of the 110K-phase material.
