Description

Current-voltage characteristics and dV/dI curves of a YBCO/Nb bulk junction at 4.2 K are reported. The presence of the Josephson effect is clearly shown. The dV/dI spectrum shows sharp structures which can be related to the Niobium and the YBCO energy gaps Δ/sub Nb/ and Δ/sub YBCO/. A value Δ/sub YBCO/ = 26.2 +- 1.0 meV can be estimated, confirming the strong coupling character of such a compound
