  • Magnetic devices
    Patent number: 7641389
    Abstract: A sensor comprises a reference sample arranged to be subject to at least one variable physical parameter such that a variation in the value of the at least one variable physical parameter causes a change in the magnetisation of the reference sample, means for measuring the magnetisation of the reference sample, and means for determining in dependence upon the measured magnetisation whether there has been a variation in the value of the at least one variable physical parameter, wherein the reference sample comprises a Heusler alloy.
    Type: Grant
    Filed: March 15, 2007
    Date of Patent: January 5, 2010
    Assignee: Kabushiki Kaisha Toshiba
    Inventors: Anke Husmann, Michael Pepper

  • Large magnetoresistance in non-magnetic silver chalcogenides and new class of magnetoresistive compounds
    Patent number: 6316131
    Abstract: The heavily-doped silver chalcogenides, Ag2+&dgr;Se and Ag2+&dgr;Te, show magnetoresistance effects on a scale comparable to the “colossal” magnetoresistance (CMR) compounds. Hall coefficient, magnetoconductivity, and hydrostatic pressure experiments establish that elements of narrow-gap semiconductor physics apply, but both the size of the effects at room temperature and the linear field dependence down to fields of a few Oersteds are surprising new features.
    Type: Grant
