  • 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.
