Chen, Y.T. (author)In this thesis, we report several effects in spintronics and spin caloritronics related to relativistic spin-orbit coupling. In Chapter 2, we discuss the relativistic spin caloritronicHall effects in terms of a semiclassical theory for anomalous thermoelectric effects in ferromagnetic metals due to spin-orbit scattering at impurities, including...doctoral thesis 2014

(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

(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

(author), Takahashi, S. (author), Gross, R. (author), Bauer, G.E.W. (author), Goennenwein, S.T.B. (author), Saitoh, E. (author)We report anisotropic magnetoresistance in Pt|Y3Fe5O12 bilayers. In spite of Y3Fe5O12 being a very good electrical insulator, the resistance of the Pt layer reflects its magnetization direction. The effect persists even when a Cu layer is inserted between Pt and Y3Fe5O12, excluding the contribution of induced equilibrium magnetization at the...journal article 2013

(author)We present a theory of the spin Hall magnetoresistance (SMR) in multilayers made from an insulating ferromagnet F, such as yttrium iron garnet (YIG), and a normal metal N with spin-orbit interactions, such as platinum (Pt). The SMR is induced by the simultaneous action of spin Hall and inverse spin Hall effects and therefore a nonequilibrium...journal article 2013
