Abstract
A quantitative analysis of the temperature dependence of modulated mic rowave absorption measurements in a sputtered film, a single crystal a nd a ceramic sample reveals two different types of intrinsic Josephson contacts. By modelling the complete temperature dependence of the mic rowave absorption signal, we were able to distinguish SNS- and SIS-typ e junctions. As a result we found SIS-type junctions for the granular (sputtered) layer, whereas the single crystal reveals SNS-typejunction s.
