We studied thec-axis transport in the high qualityBi-2212stacked junctions fabricated by the double-sided focused ion beam (FIB) processing of the single crystal whiskers. We found the value of the critical current to be considerably (by factor 30) below the value given by the Ambegaokar-Baratoff (AB) relation in the BCS model at low temperatures. The results are discussed as a possibility of thed-wave partially coherent interlayer tunneling. ©1999 American Institute of Physics.
