Abstract: The synthetic antiferromagnet [(Co$_{0.88}$Fe$_{0.12}$)/Cu]$_{N}$ which is planar composite with $\sim$60 nm thickness was researched by the spin-wave resonance technique in all angles range of the applied constant magnetic field relative to normal to the film surface. Our researches demonstrate that studied multilayer film is magnetic superlattice the microwave spectrums of which demonstrate two different exchange-coupled magnetic systems. Every of these subsystems are showing itself as a series spin-wave modes on measured microwave spectrums. The dependence of magnitude of the propagation linear range of standing spin exchange wave on specimen orientation in applied magnetic field was discovered

Keywords: spin-wave resonance, synthetic antiferromagnet, exchange coupling constant.
