Abstract
The generation of spin currents in a ferromagnet/paramagnet junction from acoustically driving magnetization precession, acoustic spin pumping (ASP), in different magnetoelectric structures draws a lot of attention because it offers great opportunities for low-power microwave spintronics. Recently, we have demonstrated for the first time the generation of pure spin current (which does not include charge current) in the high overtone bulk acoustic wave resonator (HBAR) based on YIG-Pt hybrid under resonant excitation of the magnetic dynamics in YIG [N.I. Polzikova, et al., AIP Adv. 6 (2016), 56306.]. For the practical application of this method it is necessary to understand the various factors affecting its efficiency.
