  • Oscillators using magnetic domain wall and methods of operating the same
    Patent number: 8525601
    Abstract: An oscillator generates a signal using precession of a magnetic moment of a magnetic domain wall. The oscillator includes a free layer having the magnetic domain wall and a fixed layer corresponding to the magnetic domain wall. A non-magnetic separation layer is interposed between the free layer and the fixed layer.
    Type: Grant

  • Information storage devices using magnetic domain wall movement and methods of operating the same
    Patent number: 7885104
    Abstract: An information storage device includes a magnetic layer configured to store information, a first and second conductive layer. The first conductive layer contacts a first end of the magnetic layer. The second conductive layer contacts a second end of the magnetic layer. The magnetic layer includes first and second pinning regions at which magnetic domain walls are pinned. The widths of the magnetic layer at the first and second pinning regions are different.

  • Magnetic element with switchable domain structure
    Patent number: 7102477
    Abstract: A magnetic element comprises a closed loop of ferromagnetic material having an even number of magnetic domains of opposite sense. The magnetisation within the domains is in a circumferential direction, and the domains have leading and trailing walls extending from the inside to the outside of the loop. The magnetic element has a geometry such that there are at least two stable equilibrium domain configurations in which the domain walls are confined in predetermined portions of the loop and wherein the element is switchable between the stable configurations upon the application of a external magnetic field.
