Spin transport properties in a naphthyl diamine derivative film investigated by the spin pumping
Yuichiro Onishi, Yoshio Teki, Eiji Shikoh
We report the spin transport properties in a thin film of a naphthyl diamine derivative: N,N'-Bis(naphthalen-1-yl)-N,N'-bis(phenyl)-2,2'-dimethylbenzidine (alpha-NPD). In a palladi…
An energy harvesting technology controlled by ferromagnetic resonance
Yuta Nogi, Yoshio Teki, Eiji Shikoh
We have successfully demonstrated electrical charging using the electromotive force (EMF) generated in a ferromagnetic metal (FM) film under ferromagnetic resonance (FMR). In the c…
Spin injection into vanadium dioxide films from a typical ferromagnetic metal, across the metal-insulator transition of the vanadium dioxide films
Kazuma Tamura, Teruo Kanki, Shun Shirai +3
A vanadium dioxide VO2 film shows metal-insulator transition (MIT) induced by changing environmental temperature. We report the temperature dependence of electromotive force proper…
Pure spin current in a robust pigment-red film
Kazuhiro Nishida, Yoshio Teki, Eiji Shikoh
We report the spin current properties in a pigment-red (perylene-3,4,9,10-tetracarboxylic dianhydride: PTCDA) film prepared by thermal evaporation. In a palladium(Pd)/PTCDA/Ni80Fe2…
Electromotive forces generated in 3d-transition ferromagnetic metal films themselves under their ferromagnetic resonance
Kazunari Kanagawa, Yoshio Teki, Eiji Shikoh
We report the electromotive force (EMF) properties generated in 3d-transition ferromagnetic metal (FM = Fe, Co, and Ni80Fe20) films themselves under their ferromagnetic resonance (…
Spin current relaxation time in thermally evaporated pentacene films
Yasuo Tani, Takuya Kondo, Yoshio Teki +1
The spin current relaxation time [tau] in thermally evaporated pentacene films was evaluated with the spin-pump-induced spin transport properties and the charge current transport p…
Spin-pump-induced spin transport in a thermally-evaporated pentacene film
Yasuo Tani, Yoshio Teki, Eiji Shikoh
We report the spin-pump-induced spin transport properties of a pentacene film prepared by thermal evaporation. In a palladium(Pd)/pentacene/Ni80Fe20 tri-layer sample, a pure spin-c…
Spin pumping using an Ni80Fe20 thin film annealed in a magnetic field
Hideki Shimogiku, Naoyuki Hanayama, Yoshio Teki +2
Spin pumping controlled with the ferromagnetic resonance of an Ni80Fe20 thin film annealed in a magnetic field was performed in order to investigate the simple and efficient genera…
