Abstract

We report structural and magnetic properties of Ni83Fe17/Cu multilayer films with various buffer layer and sublayer thicknesses of copper dcu and Permalloy dp y deposited by face-to-face sputtering. The following features prove a good quality of our films: a well-layered structure, complete antiferromagnetic coupling with a low coupling strength (2 x 10 -5 J/m2 for dcu = 1 nm and 10 -5 J/m2 for dc = 2.1 nm) and a low coercive field which make them attractive for possible applications as giant magnetoresistance sensors.
