TL;DR: Experimental evidence is shown that spin pumping enables spin injection free from this condition; room-temperature spin injection into GaAs from Ni(81)Fe(19) through an Ohmic contact is demonstrated through dynamical spin exchange, and this exchange can be controlled electrically by applying a bias voltage across a Ni( 81) Fe(19)/GaAs interface, enabling electric tuning of the spin-pumping efficiency.
Journal ArticleDOI
Spin Hall Magnetoresistance in Metallic Bilayers
TL;DR: A model is developed to account for the absorption of the longitudinal spin current to the FM layer, one of the key characteristics of a metallic ferromagnet, and finds a nearly tenfold increase of SMR in W/CoFeB compared to previously studied HM/ferromagnetic insulator systems.

Linear-response theory of spin Seebeck effect in ferromagnetic insulators
TL;DR: In this article, a linear response theory of the spin Seebeck effect was proposed, i.e., a spin voltage generation from heat current flowing in a ferromagnet.
