Bertram Josef Batlogg 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).

  • Patent number: 7135438
    Abstract: A class of superconductive materials containing copper-oxygen bonding and with mixed cation-occupancy designed with a view to size and valence consideration yield useful values of critical temperature and other properties. Uses entail all applications which involves superconducting materials such as magnets and transmission lines which require continuous superconductivity paths as well as detectors (e.g., which may rely on tunneling).
    Type: Grant
    Filed: April 19, 1993
    Date of Patent: November 14, 2006
    Assignee: Lucent Technologies Inc.
    Inventors: Bertram Josef Batlogg, Robert Joseph Cava, Robert Bruce van Dover

  • Patent number: 6630425
    Abstract: Superconducting copper oxides of the perovskite structure are modified to have mixed occupancy of a cation site, thereby resulting in increased limits in critical field and/or critical current. Mixed occupancy may be observed in terms of increased resistivity as the superconducting material reverts to a nonsuperconducting state. A significant advantage, at least for preferred compositions, derives from the fact that critical temperature is unaffected relative to the prototypical material.

  • Patent number: 5767673
    Abstract: Magnetoresistive elements according to this invention comprise magnetically soft material in close proximity to the magnetoresistive material, exemplarily a perovskite manganite. The combination results in magnetic field "amplification", with large resistance changes attainable at relatively low applied fields. The invention exemplarily is embodied in magnetic sensors, e.g., magnetoresistive read/write heads.
