Disclosed are an oxide superconductor tape and a method of manufacturing the oxide superconductor tape capable of improving the length and characteristics of superconductor tape and obtaining stabilized characteristics across the entire length thereof. A Y-class superconductor tape (), as an oxide superconductor tape, comprises a tape () further comprising a tape-shaped non-oriented metallic substrate (), and a first buffer layer (sheet layer) () that is formed by IBAD upon the tape-shaped non-oriented metallic substrate (); and a second buffer layer (gap layer) (), further comprising a lateral face portion () that is extended to the lateral faces of the first buffer layer (sheet layer) () upon the tape () by RTR RF-magnetron sputtering.

Oxide superconductor cabling and method of manufacturing oxide superconductor cabling

A RE-type oxide superconducting wire having excellent angular dependence for magnetic field of Jc is obtained by finely dispersing magnetic flux pinning centers into a superconductor. A mixed solution which comprises a metal-organic complex solution including a metal element which composes a RE-type oxide superconductor whose Ba content is reduced and a metal-organic complex solution including at least one or more kinds of metals which are selected from Zr, Ce, Sn, or Ti which has a larger affinity for Ba is coated onto an intermediate layer of a composite substrate, and the assembly is then calcined to disperse artificially and finely oxide particles (magnetic flux pinning centers) including Zr. Thus, the angular dependence for magnetic field (Jc/Jc) of Jc can be remarkably improved.
