We report on planar junctions fabricated from a- and c-axis quasi-homo-epitaxial NdBa₂Cu₃O_7-/PrBa₂Cu₃O_7-/NdBa₂Cu₃O_7- (NBCO/PBCO/NBCO) multilayers. Investigations of the dependence of the maximum Josephson supercurrent on the external applied magnetic fields made it evident that the spatial variations of the critical current are due to non-uniformities assumed to be localized in the PBCO barrier layer. Well developed Shapiro steps were observed. C-axis tunnelling spectroscopy investigations provide evidence of quasiparticle tunnelling that is commonly observed for superconductor/insulator/superconductor junctions. Furthermore, it was confirmed that the NBCO layers could be incorporated in a multilayer structure without substantial degradation.
