“…Peculiarities of the dimensional resonance frequencies attributed to a nonmagnetic layer were discussed earlier in [11,12]. It was shown that an equidistant arrangement of harmonics series of the standing-wave resonant frequencies occurring in uniform magnetic film is violated in a bilayered structure.…”

“…2 and 3. The parameters used in calculations correspond to those taken in our previous work [11,12]. Figure 2 illustrates the resonant susceptibility dependence on a magnetic layer thickness for the odd harmonics number n. The letter β on the plots denotes the regions corresponding to the interface position coinciding with λ/4 (d ∼ λ/4) where λ is a MEE wavelength, the letter α denotes the regions where d ∼ λ/2, the letter γ marks the regions where the dimensional resonance is not excited.…”

“…In the previous studies [11,12] it was shown that the resonant frequencies dependences, in particular ω n (d) of a bilayer have the peculiarities that are revealed when an interface position coincides with a half-wavelength of the MEE standing wave. The shape of the peculiarities is defined by the relation between elastic parameters of a system and the type of boundary conditions.…”

A study is made of the dimensional resonances of the thickness modes of shear magnetoelastic and elastic (MEE) vibrations in a bilayered structure: magnetic-nonmagnetic dielectric. The efficiency of dimensional resonance excitation is considered. We show that the magnetic susceptibility of the thickness modes of shear MEE vibrations attains extreme values in the case when the position of an interface coincides with one half and one quarter of a MEE wavelength. The magnetic susceptibility calculated for the resonant frequencies changes in a nonmonotone way with the change of relative thickness of the magnetic layer. The form of nonmonotone regions depends on the relations between the elastic moduli of magnetic and nonmagnetic layers, the position of interface and differs for odd and even resonant frequency harmonics.

“…Magnetoelastic (ME) waves were the subject of extensive research because of the possible application of magnetoelasticity in various fields, such as optical acoustics, magnetomechanical devices and others; interest in it continues unabated [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The study of ME spectrums in the confined samples is of the most interest both from theoretical and practical point of view.…”
