Summary

TEMPERATURE AND PRESSURE DEPENDENCES OF THE CRITICAL CURRENT, THE I-V CHARACTERISTICS AND CONDUCTIVITY OF BPB CERAMIC SAMPLES PRODUCED BY VARIOUS TECHNIQUES HAVE BEEN STUDIED WITH THE OBJECT TO KNOW THE BARRIER PECULIARITIES OF INTERGRAIN BOUNDARIES OF PEROVSKITE-TYPE GRANULAR METAL-OXIDE SUPERCONDUCTORS CONTRIBUTING TO FORMATION OF TRANSPORT PROPERTIES. A STRONG DEPEDENCE OF JOSEPHSON AND SINGLE-PARTICLE TUNNELING EFFECTS ON THE SURFACE STATE OF GRAINS, INFLUENCING THE GRAIN BOUNDARY COUPLING FORCES, WAS FOUND.
