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
Observation of longitudinal spin-Seebeck effect in magnetic insulators
Ken-ichi Uchida,Hiroto Adachi,Takeru Ota,Hiroyasu Nakayama,Sadamichi Maekawa,Eiji Saitoh,Eiji Saitoh +6 more
TL;DR: In this paper, a longitudinal spin-Seebeck effect (SSE) is proposed, in which a magnon-induced spin current is injected parallel to a temperature gradient from a ferromagnet into an attached paramagnetic metal.
Journal ArticleDOI
Long-range spin Seebeck effect and acoustic spin pumping
Ken-ichi Uchida,Hiroto Adachi,Toshu An,Takeru Ota,Masaya Toda,Burkard Hillebrands,Sadamichi Maekawa,Eiji Saitoh +7 more
TL;DR: This finding provides a persuasive answer to the long-range nature of the spin Seebeck effect, and opens the door to 'acoustic spintronics' in which sound waves are exploited for constructing spin-based devices.
Journal ArticleDOI
Acoustic spin pumping as the origin of the long-range spin Seebeck effect
Ken-ichi Uchida,Hiroto Adachi,Toshu An,Takeru Ota,Masaya Toda,Burkard Hillebrands,Sadamichi Maekawa,Eiji Saitoh +7 more
TL;DR: In this paper, the long-range spin voltage induced by the spin Seebeck effect in magnetic metals is attributed to phonons, which can be used to construct spin-based devices.
Journal ArticleDOI
Thermal spin pumping and magnon-phonon-mediated spin-Seebeck effect
Ken-ichi Uchida,Takeru Ota,Hiroto Adachi,Jiang Xiao,T. Nonaka,Y. Kajiwara,Gerrit E. W. Bauer,Gerrit E. W. Bauer,Sadamichi Maekawa,Eiji Saitoh,Eiji Saitoh +10 more
TL;DR: The phonon-mediated non-equilibrium that drives the thermal spin pumping is confirmed also by temperature-dependent measurements, giving rise to a giant enhancement of the SSE signals at low temperatures.
