15. In order to ensure the quality of the YIG/Pt interface, we tested the YIG-Pt sample using the ferromagnetic resonance technique (see Ref.). The ISHE voltage reached values up to 1. 5 mV for an applied microwave power of 1 W.
16. The spin wave excitation using DC current (see Refs. and) is desirable for further investigations.

18. In order to avoid any heating effects, the long repetition rate of 20 ms has been used.
19. The increase of the SW intensity with s occurs due to the better passing of the input pulse spectrum through the limited SW frequency band.

22. This value of corresponds to resonance linewidth H = 0. 8 Oe which is larger than the literature values of 0.1-0.2 Oe. This increase of the DESW damping under the Pt antenna might be caused by the additional DESW losses due to the spin-pumping mechanism.

25. The region left to the point k 0 corresponds to the magnetostatic surface spin-wave mode propagating under some angle to the bias magnetic field. No dependence of spin-pumping efficiency on the SW wavenumbers is visible here as well.
