“…Mutual posi-tion of these two peaks in FMR spectrum of films of Fe 20 Ni 80 (50 nm)/Cu(t Cu )/Fe 20 Ni 80 (50 nm) (spectra examples are in Fig. 2) allowed to define the value of interlayer exchange interaction J 12 and its sign Dependencies of values of exchange interaction of ferromagnetic layers J 12 (dashed line) and exchange interaction constants for exchange spin waves (solid line) on copper layer thickness [20].…”

“…We should note the works with registered compound microwave spectra of exchange-coupled three-layer films in perpendicular geometry of the experiment [17][18][19][20][21]; it should be noted, that in [20,21] the heterogeneous FMR is identified as SWR spectrum, where intensive observed peaks are acoustic SWR modes, accompanied by optical satellites. Established in [20,21] original fact of non-quadratic dependence H res (n) of optical satellites of exchange spin-wave modes raised several new questions: if these modifications of dispersion relation are the permanent property of optical modes, and if other power dependences are possible, what parameter defines degree of n.…”

“…Taking into account, that the results of the works [20,21] were obtained for films at symmetric boundary conditions and with magnetization fixation on a surface of " easy axis" type, we synthesized new samples of planar structures with ferromagnetic and antiferromagnetic exchange coupling at other boundary conditions of exchange spin waves fixation on surface.…”

The spectrums of standing exchange spin waves into magnetic sandwich Ni80Fe20/Cu(tCu)/Ni80Fe20 were studied by spin-wave resonance method. The layer of diamagnetic Cu depending on its thickness tCu provided 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 Hacres(n)~ n2 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 Hopres(n)~ n5/2 or Hopres(n)~ n2 depending on the boundary conditions established on inner interfaces. Keywords: spin-wave resonance, surface anisotropy constant, exchange interaction constant, interlayer exchange interaction.

“…Most of the works are devoted to the study of the exchange-coupled films in which the transition metal (Cr, Ru, Cu, V, Au) [3][4][5][6] was chosen as the intermediate layer material. One of the main results is the dependence of the exchange interaction type (sign J 12 ) on the intermediate layer thickness.…”

Three-layer FeNi/Dy/FeNi films were studied by ferromagnetic resonance method in the temperature range from 4 to 300 K. The acoustic and optical peaks recorded in microwave spectra demonstrate the presence of exchange coupling between the ferromagnetic FeNi layers of the planar system and allow us to establish the sign and value of the constant of the interlayer exchange interaction. Temperature dependences of the interlayer exchange interaction constant for three-layer films with intermediate layer thicknesses Dy 5 and 10 nm show a number of features (change in sign and extremum point), which reflect transformations of the magnetic structure Dy. Keywords: interlayer exchange coupling, helical magnetic structure, ferromagnetic resonance, three-layer films.
