Robustness of Spin Polarization in Graphene-based Spin Valves
Masashi Shiraishi, Megumi Ohishi, Ryo Nouchi +3
Decrease of spin polarization in spintronics devices under an application of bias voltage is one of currently important problems which should be solved. We reveal unprecedented rob…
A Nuclear Magnetic Resonance Study on Rubrene-cobalt Nano-composites
Masashi Shiraishi, Haruka Kusai, Ryo Nouchi +5
We implemented a nuclear magnetic resonance (NMR) study on rubrene(C42H28)-Co nano-composites that exhibit an enhanced magnetoresistance (MR) ratio of 80%. The 59Co NMR spin echo e…
Spin Injection into a Graphene Thin Film at Room Temperature
Megumi Ohishi, Masashi Shiraishi, Ryo Nouchi +3
We demonstrate spin injection into a graphene thin film with high reliability by using non-local magnetoresistance (MR) measurements, in which the electric current path is complete…
Effect of Joule heating in current-driven domain wall motion
A. Yamaguchi, H. Tanigawa, T. Ono +4
It was found that high current density needed for the current-driven domain wall motion results in the Joule heating of the sample. The sample temperature, when the current-driven…
Propagation of a magnetic domain wall in magnetic wires with asymmetric notches
A. Himeno, T. Okuno, S. Kasai +4
The propagation of a magnetic domain wall (DW) in a submicron magnetic wire consisting of a magnetic/nonmagnetic/magnetic trilayered structure with asymmetric notches was investiga…
Real-space observation of current-driven domain wall motion in submicron magnetic wires
Akinobu Yamaguchi, Teruo Ono, Saburo Nasu +3
Spintronic devices, whose operation is based on the motion of a magnetic domain wall (DW), have been proposed recently. If a DW could be driven directly by flowing an electric curr…
