  • Magnetic devices and structures
    Patent number: 8284594
    Abstract: Magnetic devices, magnetoresistive structures, and methods and techniques associated with the magnetic devices and magnetoresistive structures are presented. For example, a magnetic device is presented. The magnetic device includes a ferromagnet, an antiferromagnet coupled to the ferromagnet, and a nonmagnetic metal proximate to the ferromagnet. The antiferromagnet provides uniaxial anisotropy to the magnetic device. A resistance of the nonmagnetic metal is dependent upon a direction of a magnetic moment of the ferromagnet.
    Type: Grant
    Filed: September 3, 2009
    Date of Patent: October 9, 2012
    Assignee: International Business Machines Corporation
    Inventors: Guohan Hu, Jonathan Zanghong Sun
