Determination of the Dzyaloshinskii-Moriya interaction using pattern recognition and machine learning
Masashi Kawaguchi, Kenji Tanabe, Keisuke Yamada +4
Machine learning is applied to a large number of modern devices that are essential in building energy efficient smart society. Audio and face recognition are among the most well-kn…
Electrical detection of magnetic states in crossed nanowires using the topological Hall effect
Kenji Tanabe, Keisuke Yamada
We used micromagnetic simulations to investigate the spatial distributions of the effective magnetic fields induced by spin chirality in crossed nanowires with three characteristic…
Soliton-like magnetic domain wall motion induced by the interfacial Dzyaloshinskii-Moriya interaction
Yoko Yoshimura, Kab-Jin Kim, Takuya Taniguchi +7
Topological defects such as magnetic solitons, vortices, Bloch lines, and skyrmions have started to play an important role in modern magnetism because of their extraordinary stabil…
Switching of the Magnetic Vortex Core in a Pac-man Disk using a Single Field-Pulse
Tomonori Sato, Keisuke Yamada, Yoshinobu Nakatani
We report on the switching of the magnetic vortex core in a Pac-man disk using a magnetic field pulse, investigated via micromagnetic simulations. The minimum core switching field…
Switching magnetic vortex core by a single nanosecond current pulse
Keisuke Yamada, Shinya Kasai, Yoshinobu Nakatani +2
In a ferromagnetic nanodisk, the magnetization tends to swirl around in the plane of the disk and can point either up or down at the center of this magnetic vortex. This binary sta…
Probing the spin polarization of current by soft X-ray imaging of current-induced magnetic vortex dynamics
Shinya Kasai, Peter Fischer, Mi-Young Im +5
Time-resolved soft X-ray transmission microscopy is applied to image the current-induced resonant dynamics of the magnetic vortex core realized in a micronsized Permalloy disk. The…
