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)
