(author), Goennenwein, S.T.B. (author)We report the observation of current-induced spin torque resonance in yttrium iron garnet/platinum bilayers. An alternating charge current at GHz frequencies in the platinum gives rise to dc spin pumping and spin Hall magnetoresistance rectification voltages, induced by the Oersted fields of the ac current and the spin Hall effect-mediated spin...journal article 2015

Chiba, T. (author), Schreier, M. (author), Bauer, G.E.W. (author), Takahashi, S. (author)The spin-torque ferromagnetic resonance (ST-FMR) in a bilayer system consisting of a magnetic insulator such as Y3Fe5O12 and a normal metal with spin-orbit interaction such as Pt is addressed theoretically. We model the ST-FMR for all magnetization directions and in the presence of fieldlike spin-orbit torques based on the drift-diffusion spin...journal article 2015

Kamra, A. (author), Schreier, M. (author), Huebl, H. (author), Goennenwein, T.B. (author)We present a generic theoretical model for torque differential magnetometry (TDM)—an experimental method for determining the magnetic properties of a magnetic specimen by recording the resonance frequency of a mechanical oscillator, on which the magnetic specimen has been mounted, as a function of the applied magnetic field. The effective...journal article 2014

Schreier, M. (author), Kamra, A. (author), Weiler, M. (author), Xiao, J. (author), Bauer, G.E.W. (author), Gross, R. (author), Goennenwein, S.T.B. (author)We calculate the phonon, electron, and magnon temperature profiles in yttrium iron garnet/platinum bilayers by diffusive theory with appropriate boundary conditions, in particular taking into account interfacial thermal resistances. Our calculations show that in thin film hybrids, the interface magnetic heat conductance qualitatively affects the...journal article 2013

(author), Bauer, G.E.W. (author), Saitoh, E. (author), Goennenwein, S.T.B. (author)We experimentally investigate and quantitatively analyze the spin Hall magnetoresistance effect in ferromagnetic insulator/platinum and ferromagnetic insulator/nonferromagnetic metal/platinum hybrid structures. For the ferromagnetic insulator, we use either yttrium iron garnet, nickel ferrite, or magnetite and for the nonferromagnet, copper or...journal article 2013
