Bartur, M

A superconductor structure is described comprising: a substrate defining a surface; a barrier layer of about 0.1-200 [mu]m thickness applied to the surface of the substrate, the barrier layer comprising copper and oxygen and an element selected from the group consisting of Ba, Y and La and mixtures thereof and having a perovskite crystal structure; and a layer of a ceramic superconductive material applied to the barrier layer, comprising a composition represented by the formula: Re[sub 1]Ba[sub 2]Cu[sub 3]O[sub (7[minus]x)] wherein Re is a rare earth element selected from the group consisting of Er, Gd, Y, Tm, Sm, Eu, Dy, Ho, Yb, Nb and Lu and 0 [le] x [le] 0.5; said barrier layer reducing interaction, but increasing adhesion, between the substrate and the layer of ceramic superconductive material.
