We have investigated the magnetic structure and coupling in epitaxial [Fe-3/Au(001)(N)/(Fe1Au1)(3)/Au(001)(N)] x 2 multilayers. Our system contains alternating (Fe1Au1)(3) monoatomic stacks with perpendicular magnetic anisotropy and 3 atomic layer (AL) thick Fe films (Fe-3) with an in-plane easy magnetization axis, separated by an Au(001) spacer layer. Giant magnetoresistance and magnetization measurements as a function of N = 4, 5, ..., 24 AL of the Au spacer revealed different non-collinear magnetic alignment of the sub-layer magnetization, dependent on the interlayer exchange coupling.
