Critical current and resistance of a single grain boundary in bulk bicrystals of the oxide superconductor BaPb1−xBi x 03 show a reentrant behavior in the temperature region below critical temperature of single crystal blocks. We established that the reentrant behavior is related to intrinsic properties of a barrier of single grain boundary Josephson junctions in the bicrystals. Origin and structure of the tunneling barrier in the bicrystals under study are discussed.
