摘要： A superconductor comprising a composite oxide of rare earth elements (RE), barium and copper, wherein RE2BaCuO5 phases (211 phases) are finely dispersed in a single crystal REBa2Cu3O7-x phase (123 phase) and the 123 phase is composed of a multiplicity of layers corresponding to the composition of the RE arranged in the order of the 123 phase forming temperature; and a process for producing the superconductor which comprises forming a layer from a powdery mixture of oxides of the RE, barium and copper and also layers from other powdery mixtures of oxides of RE, barium and copper corresponding to other compositions of RE having different 123 phase forming temperatures from that of the abovementioned composition of RE to give a multilayered structure wherein the multiplicity of the layers are laminated in the ascending or descending order of the 123 phase forming temperatures thereof, press forming the laminate into a precursor, placing the precursor on a support material in such a manner that the layer having the highest 123 phase forming temperature among them forms the outermost layer, bringing it into a semi-molten state by heating in a temperature range where solid and liquid are coexistent, and cooling it slowly in the 123 phase forming temperature range, optionally after seeding with seed crystals, to grow 123 phase crystals at a rate of 5 mm/hr or less.

摘要： The present invention concerns an enhancement of the supercurrent carrying capabilities of bicrystalline or polycrystalline high-Tc superconductors, i.e. the critical current densities in such superconductors. The current transport properties are improved by chemically altering, especially doping, the superconductors. It seems that a modification of the space-charge layers at the boundary, e.g. by an increase of the mobile charge carrier concentrations particularly in the superconductor's grain boundaries, which concentrations differ from those resulting in optimum superconducting properties of the grains, are responsible for this positive effect.

摘要： A strongly-linked polycrystalline oxide superconductor article includes an oxide superconductor selected from the group consisting of 124-type and 247-type oxide superconductors having fine, highly aligned oxide superconductor grains less than 50 mu m along a longest dimension. The oxide superconductor article has at least a 25 % retention of critical current density in a 0.1 Tesla field. A method for preparing a strongly-linked oxide superconductor includes shaping a finely divided metallic precursor of an oxide superconductor; oxidizing the finely divided metallic precursor to produce a finely divided sub-oxide species while avoiding conversion of an appreciable amount of the sub-oxide species into the oxide superconductor; annealing and deforming the article, in either order, the annealing carried out at a temperature and for a time sufficient to convert some of the sub-oxide species into fine grains of the oxide superconductor thereby forming a mixture of sub-oxide species and oxide superconductor and the deformation carried out such that the fine grains of oxide superconductor are rotated into alignment parallel to an intended current carrying direction of the article without fracturing or pulverization of the oxide superconductor grains; alternating annealing and deformation of the article until no further improvement in alignment is observed; and subjecting the aligned grains to a final anneal in order to react any remaining sub-oxide species and maximize the growth and sintering of existing aligned grains.

摘要： Polycrystalline high-Tc superconductors of general formula MmEeROx, composed of essentially crystallographically oriented granules, in which M is at least a trivalent element, such as a lanthanide, E is at least a divalent element, such as an alkaline earth element, R is at least a transition metal, such as Cu, and x is the oxygen content, are prepared by substituting some of the alkaline earth element by a foreign element, preferably an alkaline element, the content of which, after reaction sintering and sintering, will no longer lie in the parts per million to parts per thousand range and which will bring about a change of orientation. The resulting material has a slightly lower E and possibly M content and the same transition temperature, and has a substantially greater stability to external influences than corresponding known materials. A subsequent treatment in a current of air or oxygen is not necessary. Monocrystals of relatively large dimensions can also be prepared in the same way.

摘要： The films of this invention are high temperature superconducting (HTS) thin films specifically optimized for microwave and RF applications. In particular, this invention focuses on compositions with a significant deviation from the 1:2:3 stoichiometry in order to create the films optimized for microwave/RF applications. The RF/microwave HTS applications require the HTS thin films to have superior microwave properties, specifically low surface resistance, Rs, and highly linear surface reactance, Xs, i.e. high JIMD. As such, the invention is characterized in terms of its physical composition, surface morphology, superconducting properties, and performance characteristics of microwave circuits made from these films.

摘要： An oxide superconductor having a superconductive layer interposed between two blocking layers compositionally different from each other. A superconductive layer is provided in any of the following structures: a single layer of one Cu-O2 surface (single layer system); a double layer system containing two Cu-O2 surfaces with a mediating layer interposed between said two surfaces; and a triple layer system containing three Cu-O2 surfaces with a mediating layer interposed between respective Cu-O2 surfaces. Because of difference in composition between the blocking layers, seventy seven (77) kinds, far more than before, of oxide and application thereof to a wider field is possible.
