Abstract. Using the inverse spin Hall effect (ISHE), spin pumping by traveling surface waves (MSSW) and backward volume waves (BVMSW) in YIG/Pt microstructures has been experimentally studied. It has been discovered that the frequency dependence of the emf U_ISHE(f), generated due to the ISHE, in the case of BVMSW is characterized by a maximum near the frequency of the long-wave (f₀) spectrum boundary. In the case of a MSSW, the dependence U_ISHE (f) exhibits maxima both at the frequency f₀ and at the frequency f_s of the short-wave boundary of the MSSW spectrum. The indicated differences in the dependences U_ISHE (f) for MSSW and OOMSW are explained by the difference in the functions of the density of states of spin waves in the spectrum of MSSW and BVMSW.

Key words: magnon spintronics, spin current, surface magnetostatic waves, backward volume magnetostatic waves, inverse spin Hall effect, YIG/Pt, van Hove singularities.
