“…When the charge carriers velocity tends to the phase velocity of the MSSW, the BG for the MSSW in the MC/SC structure approaches the BG in the MC/dielectric structure. This effect was observed earlier in the linear case at low input signal power [17]. The dependence of the BGs shift ∆f = f nl − f U on the applied electric field at different input signal powers is shown in figure 1(c).…”

Dispersion equation for the MSSW in layered structure consisted of ferromagnetic film with the constant thickness d and semi-infinite SC with the arbitrary surface conductivity Y will take the form:…”

“…In this case interaction of direct and reflected waves forms the BG for MSSW. Detailed mechanism of the BG formation is described in [17]. Let us choose the input signal frequency in the center of the BG in the linear case, then V 0,−1 = V, κ 0,−1 = κ, β 0,−1 = β, η 0,−1 = η, where η = ω BG − ω-the detuning of the signal frequency from the central frequency of the BG at a given value of the drift velocity, ω 2…”

“…Such structures, called magnonic crystals (MCs), due to the formation of band gaps (BGs)-reject bands in the spectrum of spin waves, are functionally more flexible and have greater possibilities for controlling the characteristics [2,14,15]. In periodic ferrite/SC heterostructures of the YIG/Si type, an additional opportunity appears to control the position of Bragg BGs in the spin wave spectrum and conditions of their formation using an electric current in a SC [16,17].…”

The main features of the nonlinear spin wave propagating in the magnonic crystal/semiconductor layered heterostructure are studied. We demonstrate the possibility of double electric and magnetic control of the gap solitons parameters (their number, threshold of formation, velocity), bistability of spin waves, switching powers and nonlinear band gap shift in investigated structure. Our results show the possibility of nonlinear magnonics and semiconductor electronics integration based on the proposed structure.

The paper reports on laser-induced Bragg resonances in the spectrum of magnetostatic waves in a heterostructure based on a ferrite film [yttrium iron garnet (YIG)] with periodic strips of semiconductor material (Si) on the surface. Laser irradiation of such a structure leads to the formation of Bragg bandgaps due to the modulation of the Si conductivity on the YIG surface, and the magnitude modulation increases with increasing laser radiation intensity. It is shown that an increase in laser radiation intensity also leads to an increase in the depth and frequency shift of the bandgaps.
