Patents by Inventor Susan E. G. Slusky

Susan E. G. Slusky has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Bismuth-iron garnets with large growth-induced magnetic anisotropy
    Patent number: 5021302
    Abstract: High magnetic anisotropy is achieved in bismuth-iron garnet materials which comprise a significant amount of europium, samarium, or terbium. Such materials may be made in the form of epitaxial layers grown on a nonmagnetic substrate, e.g., in the manufacture of magnetic bubble devices. On account of significant Faraday rotation, such materials may also be used in magnetic-optical devices.
    Type: Grant

    Date of Patent: June 4, 1991
    Assignee: AT&T Bell Laboratories

  • Hysteretic SIS junction mixer
    Patent number: 4325144
    Abstract: The present invention relates to a subharmonically pumped hysteretic superconductor-insulator-superconductor (SIS) junction mixer. The hysteretic junction (10), achieved by not suppressing the critical current I.sub.c of the junction, is responsive to a first source of a pump signal (12) at a frequency .omega..sub.p and a second source of an input signal (14) at a frequency .omega..sub.i, to produce a non-zero output signal at a frequency .omega..sub.o =.vertline..omega..sub.i -2.omega..sub.p .vertline., during either an overpumped or underpumped condition. The hysteretic nature of the junction allows the mixer to operate in a switching mode, thereby producing low-noise mixing with gain.
