Abstract

We have fabricated PrBa ₂ [Cu _1-x Ga _x ] ₃ O ₇ (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 PrBa ₂ Cu ₃ O ₇ (Pr123) while the other physical properties remain much the same. PBGCO therefore may be a possible buffer layer for YBa ₂ Cu ₃ O _7-δ (Y123) superlattices/multilayers. For this reason YBa ₂ Cu ₃ O _7-δ /PrBa ₂ (Cu _0.8 Ga _0.2 ) ₃ O ₇ (Y123/PBCGO) and YBa ₂ Cu ₃ O _7-δ /Y _0.4 Pr _0.6 Ba ₂ Cu ₃ O ₇ (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.
