Abstract

We have measured the c-axis resistivity, magnetoresistance, current-voltage characteristics, and the maximum Josephson current Ic in magnetic fields H parallel to the c axis for a very thin mesa of a Bi2Sr2CaCu2O8+δ crystal, which is equivalent to 20 tunnel Josephson junctions in series.It is found that Ic decreases proportionally to H -1, which agrees with a recent theory and Josephson plasma resonance experiments.This provides a basis for the straightforward application of the Ambegaokar-Halperin theory to the dissipation mechanism of the c-axis transport.
