  • Permanent magnet alloys for gap magnets
    Patent number: 11649537
    Abstract: Provided are Ce/Co/Cu permanent magnet alloys containing certain refractory metals, such as Ta and/or Hf, and optionally Fe which represent economically more favorable alternative to Sm-based magnets with respect to both material and processing costs and which retain and/or improve magnetic characteristics useful for GAP MAGNET applications.
    Type: Grant
    Filed: December 10, 2018
    Date of Patent: May 16, 2023
    Assignee: Iowa State University Research Foundation, Inc.

  • Synthesis of superconducting magnesium diboride objects
    Patent number: 6591119
    Abstract: A process to produce magnesium diboride objects from boron objects with a similar form is presented. Boron objects are reacted with magnesium vapor at a predetermined time and temperature to form magnesium diboride objects having a morphology similar to the boron object's original morphology.
    Type: Grant
