Journal ArticleDOI
Observation of the spin Seebeck effect
Ken-ichi Uchida,Saburo Takahashi,K. Harii,Jun'ichi Ieda,Wataru Koshibae,Kazuya Ando,Sadamichi Maekawa,Eiji Saitoh,Eiji Saitoh +8 more
TL;DR: The spin Seebeck effect allows us to pass a pure spin current, a flow of electron spins without electric currents, over a long distance, and is directly applicable to the production of spin-voltage generators, which are crucial for driving spintronic devices.

Ken-ichi Uchida,Jiang Xiao,Jiang Xiao,Hiroto Adachi,Jun-ichiro Ohe,Saburo Takahashi,Jun'ichi Ieda,Takeru Ota,Y. Kajiwara,H. Umezawa,H. Kawai,Gerrit E. W. Bauer,Sadamichi Maekawa,Eiji Saitoh,Eiji Saitoh,Eiji Saitoh +15 more
TL;DR: In this paper, it was shown that the magnetic insulator LaY(2)Fe(5)O(12) can convert a heat flow into a spin voltage, which can then be converted into an electric voltage as a result of the inverse spin Hall effect.
Journal ArticleDOI
Electric manipulation of spin relaxation using the spin Hall effect.
Kazuya Ando,Saburo Takahashi,K. Harii,K. Sasage,Jun'ichi Ieda,Sadamichi Maekawa,Eiji Saitoh,Eiji Saitoh +7 more
TL;DR: Using the spin Hall effect, magnetization relaxation in a Ni_{81}Fe_{19}/Pt film is manipulated electrically without applying electric currents directly to the magnetic layer.
Journal ArticleDOI
Inverse spin-Hall effect induced by spin pumping in metallic system
Kazuya Ando,Saburo Takahashi,Jun'ichi Ieda,Y. Kajiwara,Hiroyasu Nakayama,T. Yoshino,Kazuya Harii,Yasunori Fujikawa,Mamoru Matsuo,Mamoru Matsuo,Sadamichi Maekawa,Eiji Saitoh,Eiji Saitoh +12 more
TL;DR: In this paper, the inverse spin-Hall effect (ISHE) induced by the spin pumping has been investigated systematically in simple ferromagnetic/paramagnetic bilayer systems, and the spectral shape of the electromotive force is well reproduced using a simple Lorentz function, indicating that the force is due to the ISHE induced by spin pumping; extrinsic magnetogalvanic effects are eliminated in this measurement.
Journal ArticleDOI
Electrically tunable spin injector free from the impedance mismatch problem.

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.
