Abstract

Magnetic and magnetotransport properties of (Ni~80~Fe~20~/Au/Co/Au)~N~ multilayers with t~Co~ = 0.6 nm and different thicknesses of Au layers (1.5 ≤ t~Au~ ≤ 2.2 nm) have been investigated. The Co layer thickness used ensures its perpendicular anisotropy. We argue that in a hysteretic region of R(H) and M(H) dependencies the reorientation of Py layers is strongly influenced by the magnetic stray fields originating from the domain structure of Co layers. The values of stray fields are determined from R(H) and M(H) measurements and are compared with the calculated ones. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
