✦ Synopsis

Current-voltage characteristics of high T ceramic superconductors were studied at liquid nitrogen

and liquid hellum temperatures In magnetlc fields from 10 -4 to 6 T. In low magnetic fields the current transport is dominated by the Josephson type intergrain couplings while in high magnetic fields by the non-Josephson ones. The important role of frozen-in flux in conduction properties was observed.
