摘要： The invention relates to a method for controlling the movement of an Abrikosov vortex of an element consisting of a supraconductive material, a so-called supraconductive element, comprising a step of inhomogeneously heating the supraconductive element with the Abrikosov vortex in a heating zone in such a way as to move the Abrikosov vortex towards the heating zone.

摘要： Superconducting Meissner effect transistors, methods of modulating, and systems are disclosed. In one aspect a disclosed transistor includes a superconducting bridge between a first and a second current probe, the first and second current probe being electrically connected to a source and a drain electrical connection, respectively and a control line configured to emit a magnetic field signal having signal strength Hsig at the superconducting bridge. In one aspect the emitted magnetic field is configured to break Cooper pairs in the superconducting bridge.

摘要： Disclosed is an arrangement including a support and a super-conductive film which is arranged thereon. The film has a plurality of holes in order to form a perforated grating. The holes are optionally round holes having increasing sizes, triangular holes, or holes which are arranged in a meandering manner in the film, and which produce improved properties in relation to signal conversion by a vortex diode and/or in a filter. A DC signal is directly removed therein without additional electronics.

摘要： A flux-pinning system comprised of a high temperature superconductor film on a carrier wherein the film is provided with a multiplicity of holes of a radius of 50 to 2000 nm serves as the basis for an electronic component which can be utilized in high frequency and radial frequency circuits and in conjunction with SQUIDs. The holes can be arranged with variable density over the film or in the form of a uniform hexagonal or square grid and the high temperature superconductor is preferably a YBa2Cu3O7 composition. The film has a configuration of a high frequency component and may be strip shaped or loop shaped.

摘要： Disclosed is a method and apparatus for strongly enhancing vortex pinning by conformal crystal arrays. The conformal crystal array is constructed by a conformal transformation of a hexagonal lattice, producing a non-uniform structure with a gradient where the local six-fold coordination of the pinning sites is preserved, and with an arching effect. The conformal pinning arrays produce significantly enhanced vortex pinning over a much wider range of field than that found for other vortex pinning geometries with an equivalent number of vortex pinning sites, such as random, square, and triangular.

摘要： Information-bearing signals are stored using high-temperature superconducting materials. Type II semiconductors, such as materials in the perovskite class, are used for recording. A vortex of electrical current is induced in a layer of the super-conductive materials which causing a magnetic field extending from the axis of the vortex. One or more vortices can be used to record one bit of information. The induced magnetic field is sensed for reading the stored information.

摘要： An oxide superconductor includes: REBa2Cu3O7-x (RE being one element selected from a “RE element group” of Pr, Nd, Sm, Eu, Gd, Y, Tb, Dy, Ho, Er, Tm, Yb, and Lu). The RE includes at least three, types of metallic elements (M1, M2, and M3), and the three types of metallic elements are any element of the RE element group selected in order. In an oxide system satisfying R(1)≦20 mol % and R(M2)≧60 mol % and R(M3)≦20 mol %, R(M1) being an average metallic element ratio of M1 in M1+M2+M3, SD(Ms)>0.15 is satisfied at a position at 50% of an average film thickness of a cross section including the c-axis, Ms being the metallic element of not larger of R(M1) and R(M3), SD(Ms) being a standard deviation/average value of a concentration of Ms.
