Abstract
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 () were bonded onto both sides of a non-oriented and non-magnetic hastelloy tape () by a normal temperature bonding process, and an Ni-3 at % W alloy tape () having a cubic texture was bonded onto the surface of the tape () by a normal temperature bonding process. Thereafter, the heat-treatment was given in a reducing atmosphere and a bonding layer () etc. was formed on the adhesive interface of each layer. Next, a (Ce, Gd)Ointermediate layer () and a CeZrOintermediate layer () by an MOD process, a CeOintermediate layer (), a YBCO superconducting film () by a TFA-MOD method, and a silver stabilization layer () were stacked sequentially on the surface of the tape (). A critical current value (Ic) of this superconductor showed 150 A.
