Inplane spin orbit torque magnetization switching and its detection using the spin rectification effect at sub-GHz frequencies

Motomi Aoki, Ei Shigematsu, Ryo Ohshima +4

Inplane magnetization reversal of a permalloy/platinum bilayer was detected using the spin rectification effect. Using a sub GHz microwave frequency to excite spin torque ferromagn…

Detection of Ferromagnetic Resonance from 1 nm-thick Co

S. Yoshii, R. Ohshima, Y. Ando +2

To explore the further possibilities of nanometer-thick ferromagnetic films (ultrathin ferromagnetic films), we investigated the ferromagnetic resonance (FMR) of 1 nm-thick Co film…

Over 1% magnetoresistance ratio at room temperature in non-degenerate silicon-based lateral spin valves

H. Koike, S. Lee, R. Ohshima +7

To augment the magnetoresistance (MR) ratio of n-type non-degenerate Si-based lateral spin valves (Si-LSVs), we modify the doping profile in the Si layer and introduce a larger loc…

Modulation of spin conversion in a 1.5 nm-thick Pd film by ionic gating

Shin-ichiro Yoshitake, Ryo Ohshima, Teruya Shinjo +2

Gate-induced modulation of the spin-orbit interaction (SOI) in a 1.5 nm-thick Pd thin film grown on a ferrimagnetic insulator was investigated. Efficient charge accumulation by ion…

Spin transport in a lateral spin valve with a suspended Cu channel

Kenjiro Matsuki, Ryo Ohshima, Livio Leiva +4

We study spin transport through a suspended Cu channel by an electrical non-local 4-terminal measurement for future spin mechanics applications. A magnetoresistance due to spin tra…
