Dipolar field effect on microwave oscillation in a domain wall spin-valve
Katsuyoshi Matsushita, Jun Sato, Hiroshi Imamura
We examined dipolar field effects on the microwave generation in the domain wall spin-valve by solving simultaneously the Landau-Lifshitz-Gilbert and Zhang-Levy-Fert diffusion equa…
Current-induced microwave excitation of a domain wall confined in a magnetic wire with bi-axial anisotropy
Katsuyoshi Matsushita, Jun Sato, Hiroshi Imamura
We studied the current-induced magnetization dynamics of a domain wall confined in a magnetic wire with bi-axial anisotropy. We showed that above the threshold current density, bre…
Simulation of current-induced microwave oscillation in geometrically confined domain wall
Katsuyoshi Matsushita, Jun Sato, Hiroshi Imamura
We studied magnetization dynamics of a geometrically confined domain wall under dc current by solving simultaneously the Landau-Lifshitz-Gilbert equation and diffusion equation for…
Current-perpendicular-to-plane magnetoresistance of a domain wall confined in a nano-oxide-layer
Jun Sato, Katsuyoshi Matsushita, Hiroshi Imamura
We theoretically study the current-perpendicular-to-plane magnetoresistance of a domain wall confined in a current-confined-path (CCP) structure made of a nano-oxide-layer (NOL). I…
Theory of spin accumulation and spin transfer torque in a magnetic domain wall
Tomohiro Taniguchi, Jun Sato, Hiroshi Imamura
We study spin accumulation and spin transfer torque in a domain wall by solving the Boltzmann equation with a diffusion approximation. We obtained the analytical expressions of spi…
Magnetic structure of domain walls confined in a nano-oxide layer
Katsuyoshi Matsushita, Jun Sato, Hiroshi Imamura
In the recent years, a spin-valve was developed with a current-confined-path structure consisting of a non-oxide-layer (NOL). We analyze magnetic structures of the current-confined…
