Peter Lubitz 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).

  • Structures with improved magnetic characteristics for giant magneto-resistance applications
    Patent number: 6171693
    Abstract: A GMR stack has at least two ferromagnetic layers (e.g.,CoFe) spaced from each other by a nonferromagnetic layer (e.g., Cu). A layer of a phase-breaking material (such as Ta or a Ta-base alloy) between the nonferromagnetic layer and at least one of the two ferromagnetic layers prevents the undesirable growth of large-grained structures in the ferromagnetic layers.
    Type: Grant
    Filed: October 27, 1998
    Date of Patent: January 9, 2001
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Peter Lubitz, Konrad Bussmann, Shu-Fan Cheng
  • Zinc oxide stabilized zirconia
    Patent number: 5800934
    Abstract: Zinc oxide stabilized zirconia containing zirconia in cubic phase is prepd by evaporating zirconia and zinc oxide and depositing zirconia and zinc oxide on an atomic scale on a substrate. The stabilized zirconia resists corrosion at high temperatures above 1000.degree. C., can be used as a part of a barrier coating, is transparent to visible light, and is electrically conducting.

    Inventors: Syed B. Qadri, Earl F. Skelton, Peter Lubitz
  • U, W, X, Y and Z-type ferrites
    Patent number: 5593612
    Abstract: A U, W, X, Y, or Z-type hexagonal ferrite and method for making such a fete are disclosed. The hexagonal ferrite has a formula as follows:N.sub.Q Zn.sub.2-z Fe.sub.H-2x Ti.sub.X M.sub.X O.sub.E A.sub.ZAccording to the method, the required weights of the oxides and carbonates are measured and then pulverized and mixed to form a material which is sintered in air. This material is then cooled to produce the U, W, X, Y, or Z-type hexagonal ferrite.
