Abstract

We have fabricated PrBa₂[Cu_1-xGa_x]₃O₇ (PBGCO) ceramic samples for x = 0.05, 0.10, 0.15 and 0.20. The electrical resistivities of these samples are many orders of magnitude higher than that of PrBa₂Cu₃O₇ (Pr123) while the other physical properties remain much the same. PBGCO therefore may be a possible buffer layer for YBa₂Cu₃O_7-δ (Y123) superlattices/multilayers. For this reason YBa₂Cu₃O_7-δ/PrBa₂ (Cu_0.8Ga_0.2)₃O₇ (Y123/PBCGO) and YBa₂Cu₃O_7-δ/Y_0.4 Pr_0.6Ba₂Cu₃O₇ (Y123/YPBCO) superlattices were fabricated and their transport properties were studied. It is found that although PBGCO is better for insulating Y123 films in trilayers, inter-Y123 layer coupling exists between separated Y123 layer.
