  • Class of ferromagnetic semiconductors
    Patent number: 8357309
    Abstract: Single crystal and polycrystal oxoruthenates having the generalized compositions (Baz,Sr1?z)FexCoyRu6?(x+y)O11 (1?(x+y)?5; 0?z?1) and (Ba,Sr)M2±xRu4?xO11 (M=Fe,Co) belong to a novel class of ferromagnetic semiconductors with applications in spin-based field effect transistors, spin-based light emitting diodes, and magnetic random access memories.
    Type: Grant
    Filed: April 3, 2008
    Date of Patent: January 22, 2013
    Assignee: University of Kentucky Research Foundation
    Inventors: Larysa Shlyk, Sergly Alexandrovich Kryukov, Lance Eric De Long, Barbara Schüpp-Niewa, Rainer Niewa
  • Process for the production of highly-textured, band-shaped, high-temperature superconductors
    Patent number: 7763569
    Abstract: A wet-chemical method for producing strip-shaped high-temperature superconductors with a substrate, optionally with a buffer layer and with a high-temperature superconductive layer is improved by increasing the texturing and the layer thickness of the high-temperature superconductive layer. To this end, precursor solutions are applied in layers to the substrate, of which the first is low in fluorine or does not contain fluorine, and the following have a fluorine concentration that increases with each layer.

    Date of Patent: July 27, 2010
    Assignee: Zenergy Power GmbH
    Inventors: Michael Bäcker, Brigitte Schlobach, Kerstin Knoth, Barbara Schüpp-Niewa, Bernhard Holzapfel, Martina Falter
  • Process for the production of highly-textured, band-shaped, high-temperature superconductors
    Patent number: 7727579
    Abstract: The formation of band-shaped HTSL on a metal substrate is disclosed. The HTSL includes at least one buffer layer comprising zirconates and/or rare-earth oxides. The HTSL layer is formed on the buffer layer. The buffer layer has a texturing that in the case of a RHEED measurement results in discrete reflexes and not only in diffraction rings. In particular, the buffer layer may be textured along its interface with the HTSL layer.
