Аннотация: <jats:p> The spectrums of standing exchange spin waves into magnetic sandwich Ni<jats:sub>80</jats:sub>Fe<jats:sub>20</jats:sub>/Cu(t<jats:sub>Cu</jats:sub>)/Ni<jats:sub>80</jats:sub>Fe<jats:sub>20</jats:sub> were studied by spin-wave resonance method. The layer of diamagnetic Cu depending on its thickness t<jats:sub>Cu</jats:sub> Показать полностьюprovided both positive and negative exchange interaction between ferromagnetic layers. It was shown that spin waves modes of SWR spectra which are described by well-known relation H<jats:sup>ac</jats:sup><jats:sub>res</jats:sub>(n)~ n<jats:sup>2</jats:sup> are standing acoustic exchange spin oscillations of individual ferromagnetic layers, regardless of a sign of interlayer exchange couple. It was detected that spin modes which are optical satellites of acoustic SWR peaks are described by the dependence of the resonance field H<jats:sup>op</jats:sup><jats:sub>res</jats:sub>(n)~ n<jats:sup>5/2</jats:sup> or H<jats:sup>op</jats:sup><jats:sub>res</jats:sub>(n)~ n<jats:sup>2</jats:sup> depending on the boundary conditions established on inner interfaces. Keywords: spin-wave resonance, surface anisotropy constant, exchange interaction constant, interlayer exchange interaction. </jats:p>
