Abstract
Magnetostatic surface waves (MSSW) propagation and electromotive force (EMF) generation effects in 14.6 µm-thick yttrium iron garnet (YIG) film covered by 8 nm-thick Pt layer was studied. It was found that MSSW dispersion k = k(f) and transmission S21(f) characteristics in the YIG/Pt structure are very similar to that of the free YIG film. For YIG/Pt structure, we show that EMF (U) demonstrates non-monotonous frequency dependence U(f) and is characterized by two peaks U1,2. The first one (U1) is located near the short-wavelength (k → ∞) cut-off frequency of the MSSW spectrum and can be attributed to MSSW drag of electrons in YIG/Pt structure. The second one (U2) is located near the long-wavelength (k → 0) cut-off frequency of the MSSW spectrum and can be attributed to the inverse spin Hall effect due to the spin pumping.
