Zhou, Y. (author), Jiao, H. (author), Chen, Y. (author), Bauer, G.E.W. (author), Xiao, J. (author)We develop a self-consistent theory for current-induced spin-wave excitations in normal metal/magnetic insulator bilayer structures. We compute the spin-wave dispersion and dissipation, including dipolar and exchange interactions in the magnet, the spin diffusion in the normal metal, as well as the surface anisotropy, spin-transfer torque, and...journal article 2013

(author), Xiao, J. (author), Chen, Y.T. (author), Jiao, H.J. (author), Bauer, G.E.W. (author), Goennenwein, S.T.B. (author)We perform a quantitative, comparative study of the spin pumping, spin Seebeck, and spin Hall magnetoresistance effects, all detected via the inverse spin Hall effect in a series of over 20??yttrium???iron?garnet/Pt samples. Our experimental results fully support present, exclusively spin current-based, theoretical models using a single set of...journal article 2013

Jiao, H. (author), Bauer, G.E.W. (author)The spin current pumped by a precessing ferromagnet into an adjacent normal metal has a constant polarization component parallel to the precession axis and a rotating one normal to the magnetization. The former is now routinely detected as a dc voltage induced by the inverse spin Hall effect (ISHE). Here we compute ac ISHE voltages much larger...journal article 2013
