Abstract
Fe/Si multilayers with strong bilinear and biquadratic couplings were inves tigated. A complex structure revealed by the Mossbauer spectroscopy corresp onds to multimode ferromagnetic resonance spectra in a non-saturated state. Simple dispersion relations for antiferromagnetic coupled bilayer structur es are shown to be inapplicable to the Fe/Si multilayers with a strong biqu adratic component to the antiferromagnetic bilinear coupling.
