摘要： This invention provides a rare earth-type tape-shaped oxide superconductor having excellent mechanical strength and superconducting properties and a composite substrate using for the same. Non-oriented and non-magnetic Ni-9 at % W alloy tapes (11, 21) were bonded onto both sides of a non-oriented and non-magnetic hastelloy tape (100) by a normal temperature bonding process, and an Ni-3 at % W alloy tape (12) having a cubic texture was bonded onto the surface of the tape (11) by a normal temperature bonding process. Thereafter, the heat-treatment was given in a reducing atmosphere and a bonding layer (50a) etc. was formed on the adhesive interface of each layer. Next, a (Ce, Gd)O2 intermediate layer (13) and a Ce2Zr2O7 intermediate layer (14) by an MOD process, a CeO2 intermediate layer (15), a YBCO superconducting film (16) by a TFA-MOD method, and a silver stabilization layer (17) were stacked sequentially on the surface of the tape (12).

摘要： RE superconductive layer of high critical current density (Jc) is superimposed on an interlayer formed so as to, while ensuring cracking prevention, excel in crystallinity, such as in-plane orientation degree and direction, and surface smoothness. On an oriented Ni substrate, there are sequentially superimposed an interlayer of cerium oxide loaded with 20 to 60 mol %, in terms of metal content, of one or at least two rare earth elements according to MOD technique and an RE superconductive layer of high Jc according to MOD technique. The above interlayer is formed by mixing a Gd, Y and/or Yb organometallic compound solution with a Ce organometallic compound solution, applying the mixed solution onto an oriented Ni substrate so as to form a coating film and subjecting the coating film to calcination heat treatment and thereafter firing in an Ar—H2 atmosphere at 950 to 1150° C. under a pressure of 50 to 500 Pa. YBCO superconductive layer is formed on this interlayer according to TFA-MOD technique.
