“…При этом с контактов к Pt, расположенных вдоль направления, перпендикулярного n, измеряют величину ЭДС U = I e R, где R -сопротивление Pt [1][2][3][4][5]. Генерация ЭДС в структурах ЖИГ−Pt бегущими СВ изучалась как в геометрии поверхностных магнитостатических волн (ПМСВ), когда волновой вектор k перпендикулярен направлению касательного поля H (k ⊥ H) [6][7][8][9][10][11][12][13][14], так и в геометрии обратных объемных магнитостатических волн (ООМСВ), когда k H [13][14][15][16]. При этом в работах [6][7][8][9][10][11][12][13]…”

In a structure of an epitaxial film of yttrium iron garnet (YIG) with crystallographic orientation (111) 11.8 μm thick and a 5 nm thick platinum (Pt) film deposited on its surface, the effect of EMF generation in a platinum film during the propagation of magnetostatic waves (MSW) in the structure was studied at values of the tangential constant magnetic field H less than the saturation field H_s~65 Oe of the YIG film. The experiments were performed in a geometry where the field H was parallel to the crystallographic direction [1¯21] and to the MSW antennas, and the distances from the input antenna to the output antenna and to the Pt film were ~5 mm and ~0.5 mm, respectively. In the structure under consideration, at |H|<H_s, a stripe domain structure (SDS) was formed, which in fields |H|<H_1~5 – 7 Oe acquired a branching character in the near-surface layer. In the range of fields H_1<|H|<H_2≈40 Oe, MSW propagation was observed in the frequency band ∆F_1~ 300-550 MHz, which was accompanied by EMF generation due to the inverse spin Hall effect. In the interval H_2<|H|≤H_s, MSW propagation was observed in the frequency band ∆F_2≈ 750-1750 MHz, while the frequency interval in which the EMF signal was recorded turned out to be several times smaller due to the development of MSW parametric instability.

“…Therefore, the structures, based on yttrium iron garnet (YIG) and platinum (Pt)metal with a strong spin-orbit coupling, are studied the most. In such structures the metal conduction electrons are sensitive to magnetization of YIG film due to exchange and spin-orbital interaction, resulting in EMF generation at spin wave propagation by means of Hall spin effect [4] or wave drag effect in conductor volume [{]5-7}. But there were no studies of dipole-exchange resonances influence on the generated EMF at SMSW propagation in Pt/YIG structures yet.…”

The characteristics of EMF (U) generation in the thin-film Pt/YIG structures caused by hybridization of propagating magnetostatic surface waves with exchange modes of YIG film were studied. It was shown that at frequencies f* corresponding to the dipole-exchange resonances (DER) the magnitude of EMF U increases by several times in comparison with the frequencies different from DER (f?f*). The Volt-Watt sensitivity was estimated for the Pt/YIG structures with different geometries of Pt microstrips. Keywords: Spintronics, spin waves, EMF generation, electron drag effect , dipole-exchange resonance.

“…В этой связи наиболее широко исследуются структуры на основе пленки железоиттриевого граната (YIG) и платины (Pt) -металла с сильной спин-орбитальной связью. В такого рода структурах электроны проводимости металла чувствительны к намагниченности пленки YIG за счет обменного и спин-орбитального взаимодействий, что приводит к генерации ЭДС при распространении спиновой волны за счет обратного спинового эффекта Холла [4] или эффекта увлечения электронов волной в объеме проводника [5][6][7]. При этом исследование влияния дипольно-обменных резонансов на генерируемую ЭДС при распространении ПМСВ в структурах Pt/YIG ранее не проводилось.…”
