Lucinski T, Urbaniak M, Stobiecki F, Hütten A, Reiss G. Py/Cu/Co/Cu spin-valve magnetoresistive multilayers with weak interlayer coupling. In: Czechoslovak Journal of Physics. CZECHOSLOVAK JOURNAL OF PHYSICS. Vol 52. INST PHYSICS ACAD SCI CZECH REPUBLIC; 2002: A165-A168.The magnetoresistive properties of [NiFe/CuAgAu/Co/CuAgAu](N) multilayers are described. It is shown that these structures exhibit large resistance changes within a small magnetic field range. It leads to high GMR field sensitivities reaching 6.8%/Oe at room temperature. Magnetoresistance effect is anisotropic with the highest resistance changes being observed for field applied parallel to an easy axis of permalloy layers
