The measured temperature variation of the maximum zero-field dc Josephson current for small Nb--NbO/sub x/--Sn junctions falls slightly under the Ambegaokar--Baratoff theoretical curve for temperatures near T/sub c/(Sn). This is consistent with measurements on Nb--NbO/sub x/--Pb junctions and may be due to proximity effects at the Nb surface.
