摘要： An oxide high temperature superconductor and method of making which includes a first buffer layer composed of CeO3 formed on a sapphire R (1, −1, 0, 2) face substrate for reducing lattice mismatch between the sapphire R (1, −1, 0, 2) face substrate and the oxide high temperature superconductor thin film, and a second buffer layer composed of such an oxide high temperature superconductor but in which Ba is substituted with Sr formed on the first buffer layer. The first buffer layer reduces the lattice mismatch between the sapphire R (1, −1, 0, 2) face substrate and the oxide high temperature superconductor thin, the second buffer layer prevents an interfacial reaction with Ba, thereby permitting the epitaxial growth of an oxide high temperature superconductor thin film that excels in both crystallographic integrity and crystallographic orientation.

摘要： A superconducting thin film is disclosed having columnar pinning centers utilizing nano dots, and comprising nano dots (3) which are formed insularly on a substrate (2) and three-dimensionally in shape and composed of a material other than a superconducting material and also other than a material of which the substrate is formed, columnar defects (4) composed of the superconducting material and grown on the nano dots (3), respectively, a lattice defect (6) formed on a said columnar defect (4), and a thin film of the superconducting material (5) formed in those areas on the substrate which are other than those where said columnar defects are formed. The superconducting thin film (5) is prepared by depositing the material other than the superconducting material on the substrate (2) while controlling the substrate (2) temperature, and the film thickness of the material deposited so to coagulate the deposited material to form the nano dots (3), and then growing a thin film of the superconducting material (5) on the substrate (2). An improved superconducting thin film is thus provided which regardless of its type is at least ten times higher in critical current density than an exiting superconducting thin film, and which can also be manufactured at a low cost. And, being large in critical superconducting current density and critical superconducting magnetic field, it is advantageously applicable to the technical fields of cryogenic electronics and microwaves.

摘要： Proposed are a selective reduction type high temperature superconductor and methods of making the same, the superconductor having a pair of charge supply layers each formed of a Cu1-xMx surface (1, 1), a first superconducting layer formed of a 5-coordination CuO2 surface (2) and a second superconducting layer formed of a 4-coordination CuO2 surface (3). Reducing M ions (e.g., Tl ions) in the charge supply layers by heat treatment in a reducing atmosphere enables the 5-coordination CuO2 surface (2) as the first superconducting layer to be over-doped and the 4-coordination CuO2 surface (3) as the second superconducting layer to be optimum-doped. According to the present invention, a high temperature superconductor is provided that with its critical temperature held high has a reduced superconducting anisotropy &ggr;, and provides a high critical current density Jc and a high c irreversibility field Hirr.
