Генерация ЭДС магнитостатическими волнами в структуре ЖИГ(111)-Pt в слабых полях подмагничивания

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