    摘要： A production process of a thick-film tape-shaped RE-type (123) superconductor having a high critical current value. The production process has the steps of providing a composite substrate having Gd2Zr2O7 and CeO2 stacked in that order onto a Hastelloy substrate, coating a raw material solution prepared by dissolving a trifluoroacetate of Y and Ba and a naphthenate of Cu onto the composite substrate, heat treating the coated composite substrate by calcination, then subjecting the calcined assembly to intermediate heat-treatment at a temperature below the temperature of heat-treatment for superconductor production, and then heat treating the assembly in an argon gas atmosphere under conditions of highest heating temperature 760° C., water vapor partial pressure 13.5%, and oxygen partial pressure 0.09% for superconductor production to produce a tape-shaped RE-type (123) superconductor having a YBCO superconducting film having a thickness of more than about 2 μm.

    摘要： 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,min/Jc,max) of Jc can be remarkably improved.

    摘要： Tape-shaped superconducting wires are made by forming a superconducting film on the substrate. At least the superconducting film is slit, electrically separated into a plurality of superconducting film parts each having a rectangular cross section and arranged in parallel to form parallel conductors. This provides superconducting wires capable of containing AC loss. A superconducting coil is made by winding the superconducting wires described above, wherein the provision of a coil structure containing at least partially a part wherein the perpendicular interlinkage magnetic flux acting among various conductor elements of the parallel conductors by the distribution of the magnetic field generated by the superconducting coils cancel mutually enables a simple structure without transposition to cancel mutually the interlinkage magnetic flux by the perpendicular magnetic field against wires, to contain circulating current within the wires by the perpendicular magnetic field and to make shunt current uniform. This provides a low-loss superconducting coil.

    摘要： The invention relates to a technique for forming a single crystalline thin film of good quality on an underlayer. Such a technique is suitably applicable to provision of an oxide high-temperature superconductor thin film usable for a superconducting wire material, a superconducting device or the like. The single crystalline thin film formed on a substratum is made of a substance different from that of the substratum. A specific atomic layer contained in common in the substratum and the thin film is shared at an interface between the substratum and the thin film. In a region as adjacent to the interface as 100 or fewer unit cells of the thin film apart from the interface, a ratio of crystalline region having grown with an orientation of ±2 degrees or less deviation angle on the basis of a crystal orientation of the substratum is 50% or more.
